This thread is an attempt to capture most of the pages from the beloved Damguy site that we have relied on for many years. Many of the pictures on the site are hosted on another site that is no longer working and would not be recoverable without legal intervention. Although the information contained herein began as a direct copy and paste from both sites, it is not intended to replace the site. More of a back up in the event it were to go down. I know much work has gone in to creating such a site and it would be a shame to lose all of the data and pictures. In the event errors are identified, I will go back and make corrections.
Not all of the pictures have been recovered. I tried to note those instances. So, if anyone has them on their local PC, please feel free to send them my way (jbrentd953 at gmail dot com) and I will make every attempt to add them.

Oscar F. Mossberg, a native of Sweden, came to the United States in 1886. Soon after his arrival he joined with the Iver Johnson Corporation in the bicycle plant. Fortunately his interests lied more in the firearms side of the plant and his unique development of the "Hammer the Hammer" action that made Iver Johnson revolvers famous.
After a few years Mossberg left Iver Johnson for a job as Superintendent of the Shattuck Arms Company, maker of fine palm pistols, revolvers and shotguns.
In 1900 he signed on with the Stevens Arms Corporation and stayed there for the next 14 years.
In 1914 he joined the newly founded Marlin-Rockwell Corporation in the manufacture and development of light machine guns. He stayed until the company went belly up in 1919.
In 1919 with the partnership of his two sons Iver and Harold, O.F. Mossberg and Sons was born. The motto of O.F. Mossberg and Sons has always been to put out a quality product at an affordable price. In their infancy that rule always applied. The profit margin was only pennies but the product was so good that the company grew in leaps and bounds.
Mossberg was a firearm innovator and had many firsts...
First to produce a man sized rifle for an affordable price.
First to offer a complete rifle and telescopic rifle sight package for one price.
First to offer a rifle with all the necessary accessories, sling, swivels, peep sights, telescopic sight, etc.
First to drop the military finger grooved forearm styling.
First to produce a spotting scope with stand at an affordable price.
First to produce a range finding telescopic sight.
In 1937 the world lost a great innovator but Oscars sons continued to follow their fathers philosophy and produce reasonably priced quality firearms and accessories for years to come.

Seems there has been allot of debate on the production dates of the 144 LSB, there are quite a few folks who purchased these rifles as early as 1967, hopefully the production dates snafu will be resolved soon.

Mounts to left side of receiver with 2 screws; elevation is adjusted with thumbscrew in conjunction with turning the 1/8 minute click knurled knob to move eyepiece to desired location, then lock into place with thumb screw; windage adjusted by loosening screw in eyepiece to desired setting, turning 1/8 minute knurled knob to move eyepiece to desired setting, retighten eyepiece to lock into place. Windage arm is spring-loaded and will swing out of way to facilitate use of scope or rear sight; black painted alloy; pre 1945.
The graduations on the elevation and windage screws with corresponding clicks, represent 1/8 minute adjustments, equivalent to 1/8" at 100 yards, 1/16" at 50 yards, or 1/32" at 25 yards. It is well to remember to move the rear sight in the direction in which it is desired to move the bullet on the target. If the rifle shoots low raise aperture by FIRST loosening elevation unlock screw slightly then turn elevation adjusting screw to the left or counter clockwise. If rifle shoots high lower aperture by FIRST loosening elevation lock screw slightly then turning elevation screw to the right or clockwise. When proper elevation is located TIGHTEN elevation lock screw. If rifle shoots to left move aperture to RIGHT by first loosening aperture disc, then turn windage adjusting nut to left or counter clockwise. If rifle shoots to right move aperture to left by FIRST loosening aperture disc then turn windage adjusting nut to right or clockwise. When proper windage is located TIGHTEN aperture disc. To swing peep sight out of way, loosen the elevation locking screw and turn peep sight until cross arm is parallel to barrel and then tighten elevation locking screw.
Mounts to left side of receiver with a large coin slotted thumbscrew that doubles a elevation lock screw. To adjust elevation loosen the thumbscrew, operate the cam to raise or lower the eyepiece to the desired height and tighten the thumbscrew to lock the setting into place. To adjust windage loosen the windage locknut, screw the windage adjusting nut until eyepiece is in desired location and retighten windage nut. There is an extra aperture included that is stored by screwing onto windage locking nut. Stamped steel and forged construction. Special thanks to Displaced Hoosier for the hang tag instructions. Detailed Instructions
When sighting a rifle for target work adjust the elevation first. If rifle shoots low, raise the rear sight by loosening elevation lock nut and moving cam to the rear or toward you. One graduation on cam will move the bullet's point of impact approximately 5/16" at 25 yards, 5/8" at 50 yards, and 1 1/4" at 100 yards. When elevation is secured, tighten lock nut.
If the rifle shoots to the left, loosen windage adjustment lock nut and turn the notched nut toward front end of the rifle. If it shoots to the right, turn the notched nut toward you. Then tighten lock nut. One quarter turn or notch is equivalent to approximately 5/32" at 25 yards, 5/16" at 50 yards, or 5/8" at 100 yards.

Parker Hale PH-16D, Mounts to left side of receiver with 2 screws, fits the Mossberg factory screw hole pattern no drilling or tapping required. This was installed onto some M42MB's as the British thought the No. 4 was an inferior sight. It is micro adjustable and swings out 90 degrees to allow the use of a rear sight. Photo (4) describes the features of sporterized rifles returned to the United States, very interesting. Special thanks to "JFK" a .22 trainer collector for the photos and information.
