Rsaf srem-1

I watched a doco on this today RSAF SREM-1 of 1944 vintage apparently the only one of its type to survive the 19 other ones supposedly made are gone.
Not sure on the concept to make such a complicated weapon understand the reasoning being a bull pup designs but a pump action, something to do with maintaining sight picture.
They were looking at two cartridges the 7.92 x 57 or the 30/06 round moving from the 303 the 7.92 was the Besa MG used by the British (1939-1966) ammo was being produced locally.
I tried to find the vid on my computer to put here but gave up you may find it on youtube on your TV it was an interesting idea but so late in the war!

Pic is of the actual rifle the scope was gone as was the front mount.

Reminds me of the Andrew Burgess shotgun from 1894. Burgess used the rear grip and
trigger as his pump handle. His shotguns sold from 1894 to 1899 until the company was
sold to Winchester. Burgess also made some pump action rifles in 30-30 and 45-70 too
