What a Pile of...

[beachdog77]

Way over on the left is something standing in the background...Jap maybe? Nambu LMG?

im going to say it might be a ZB 26, probably a Chinese capture that the Japanese then put into service. It looks like the grip has been broken off. The rear of the receiver its stepped like the ZB and is not squared off with the tube protruding out the back of the receiver like the type 96 & 99. The drum sight is further forward ( or so it seems) than on a Bren gun and the stock looks different.

funny how some of the captured japanese combat footage some times shows Japanese using BARs and some of the footage from china or singapore shows the Japanese running around with SMLEs.
