Complete butt assembly for the Swedish M/21 BAR, This is the early style Swedish BAR, possibly built by Colt, possibly by Carl Gustafs Stads. 

The wood is darker than the usual birch used by most of these guns.  The wood is in fair condtion, nicks and dings, with a crack on the front left side that follows the buffer tube.  It is missing the medalion on the stock but is double struck with the Crown proof mark

The buffer is complete, and inch pattern, you could use this on a USGI or aftermarket BAR receiver

The buttplate is rusty, and is stamped with the #7130 and the Crown proof mark

Decent parts, glue up the stock and it will be a perfectly serviceable unit.  Parts are hard to find for these, only 8,100 of these guns were built
