Gold plated triggers became a standard feature on the Marlin 336 in 1958. Straight stocked Marlin 336's are common and were marketed as the "Texan" model; but never marked on the barrel as such (in fact, most Texan barrels are stamped "RC"). Early Texan models had rounded levers, with the squared lever (similar in shape to the early Marlin Model 93 lever) variation being introduced during the early '70's. Replacement stocks can be found on eBay, various gun auction sites, Numrich Arms, etc; and thru after market parts suppliers such as Macon Gun Stocks and others, although most aftermarket stocks are unfinished and require plenty of hand fitting. There are all manner of model differences between very early and later vintage Model 336's (Ballard vs Micro-groove rifling, matted receiver tops, smooth receiver tops, smooth D&T receiver tops, hammer and trigger differences, stock differences, etc); but the absolute best place to get information on all manner of Marlin rifles and variations is by checking out the marlinowners.com forum.
Good information Tom, for the most part.
