It's happened to us all at one time or another.... mine was a Winchester model 12 in 28 ga. back in 1964 . Had I only known how few were made when I saw it in a hardware store in Sundance, WY for $85 .......... needless to say, by the time I found there were only a handfull made, it was long gone.:Welcome:
I had a guy offer to sell me his Nylon 76 18 months ago for about $100. I wasn't interested until a few days later when I saw what they were really worth. By then it was taken.
