AS you know now that IP never made type 3 recoil plate for issue. IP was only in business till March 1943 when their contract was revoked and give to Saginaw Steering Gear. SG took over all of the IP inventory, machinery and buildings. Then started making carbines using what ever was left from IP. Time wise in general July1943 for the change over to the type 3 recoil plate. So don't be confused. Just ask here and someone with correct information will answer you. Just may take longer times now and then. Their a bunch of old farts you know and don't move quick anymore.!!!!
