I have been given a Marlin 1936 in 30-30 from my father. I know very little about it. I do know it is missing it's stock. Is new wood for this old beauty hard to come by? What's a fair price if I do stumble across one? Does a stock from a different Marlin work? Will post pics later, I think based on the serial it is from 1937 but if someone has a serial number list I would love to see it. Thanks guys.
If I recall correctly, the tangs of the Marlin 1936 are longer than the 336; the pistol grip may also be a different shape/curvature. So the stock from a 336 won't necessarily fit a 1936, and probably not without at least some reshaping/inletting. Keep in mind, too, that Marlin has changed their buttplates and other details over the years, so you'll have to do some work to make a 336 stock match. I've never seen a vintage 1936 stock sold separately, so you may need some luck finding one --- I'd expect to pay $150+ if one came around, considering that 336 stocks are usually in the $75+ range.
Here's some dimensions from Boyd's replacement 336 stocks that you can check against yours: h ttp://www.boydsgunstocks.com/product.htm?pid=12694

Western Gunparts actually does carry replacement 336 stocks at a reasonable price; they often have them listed on Gunbroker. Other sources of replacements stocks, which will require fitting and finishing, are Macon Gunstocks and Precision Gunstocks --- both these are out of the US, but I've ordered replacement stocks from each and they've shipped to Canada.
