I have a Strange Remington UMC .22 cal Rolling Block lever TD that I believe to be Model 4 or 4S. The odd thing is the round barrel is 28" and the forearm is 24"and there is no handguard or barrel band that the military versions have. There is no serial number, only a D and #10 stamped on the bottom of the barrel near the receiver. On the bottom of the Buttstock near the Trigger guard is the #431 and H1.is stamped in the wood. The patent date on the barrel is July 22-1902. The metal buttplate is stamped UMC. I'm trying to get a Proper ID. If you can help or need pics email me at dokey@frontiernet.net
