My Mate found a Lion air rifle in the stream that ran through his parents garden. Bluing had gone and was a light gun metal grey, stock was pale brown and looked like it had been cut from old wash board wood. Considering it had been in the stream for at least 5 years it shot better than my BSA Mercury i had at the time. I am going back 30 odd years. From memory it was a break barrel, typical Chinese cheap looking stock and was in .177

Don't have a clue of model, don't worry about things like that when a kid
