Am considering selling my excellent condition Marlin Model 99M1, it does not have a serial number, if that helps tell it's age. It doess have the rear sight and a sling that looks to be the same vintage as the rifle. Like I stated eariler, the rifle is in very good to excelent condition, however it is missing the little bullseye that goes in the rear bottom of the stock. I have the little piece on the way from Numerich, but it in no way affects the function. For now I would prefer to keep this local in Western Washington, may consider seling at a later date. Anyone seriously interested just send me an e-mail and I can send you some pics. I am asking 225.00 for a local FTF deal, please let me know if my asking price is way out of line, as I am not desperate to sell it right now, it's a pretty cool looking little rifle. Almost forgot to add, this one has the 9 shot (I believe) tube magazine.
