The 24 inch 336As are around but I wouldn't call them standard production, especially a waffle top-which by your description--sounds like you have one. Other than they were a standard rifle that Marlin made back in the day, they are getting harder to find since fewer of them were produced. VG conditioned waffle top 336As are bringing 600-700 bucks on the online gun sales sites. Local prices can vary depending on your location. I have three 336As and all of them are fantastic shooters--I don't plan on selling them anytime soon.Thanks very much, Ret_Eng. Appreciate that.
The rifle has a 24" barrel, wavy-top receiver, and a half magazine. Pretty much standard production, as I remember it. The carbines were seen more often, but the rifles were around, too.
