I found one on EBay last year. They do come up from time to time. Mine was listed as a Rugar 28 ga. stock. Since it was miss spelled I was the only bidder and I think the only one who saw the listing. You have to spell things on EBay correctly or almost no one will see them. I have a sort list of miss spelled words that I check from time to time.
Short list examples;
Ithaca, Ithica
Ruger, Rugar
Superposed, Superpose, Superposse.
Remington 3200, Remington 32OO with OO being letters instead of 00 zeros. Some searches will not see a letter O as a Zero.
