Blood for the Baron!

Can somebody tell me which figure the gun on the tripod comes from please?

It doesn't look like the A Team gun that goes with the tri pod.
I realise this is of no help.

Yep, the gun on the tri-pod is for the -a-like sized A Team guys, the gun beneath it is Rock 'n' Roll's.

Thanks
