Antique Marlin 1894 38 40 stock question

[Henry4570]

My question is Will a 32 20 antique stock fit a 1894 38 40 marlin rifle. Were the frames/receivers the same?
My brother has an old Marlin 1894 38 40 ., year built according to the serial number is 1904.
Gun was missing the breech bolt, but I found one for a 44 40 complete. Forearm he did from one he bought from Numich I think, cut down to size, did a great job too.
Action is nice and smooth/crisp. Round barrel, straight grip, carbine model as it has the shorter barrel and magazine tube to the end.
He bought the gun with parts missing from an older guy who's intent was to rebuild the gun, but after 15 years, sold it to my brother. Goal is to get it done., but wants to keep it as original as possible.
Anyone know if the frame/receivers were the same?
Thanks

The frame sizes for all four calibers of the Model 1894 are the same. There may be a slight difference where the metal meets the wood as these were hand fitted at the time of assembly. That is why the wood was serialized to the frame so as to bring the parts back together after the finishing processes.

And carbine and rifle stocks took different buttplates, so if he wants to keep it original looking he'll need a carbine style buttstock and buttplate.

Thanks all for the information. I'll pass on the info to my brother. Greatly appreciated.
