RWD on the receiver, or barrel shank? Should be on the barrel, or barrel shank.
That would make it an East German (Suhl) refurbed M44, that was sold to Egypt (the RWD is something like "Railroad Works Department" - because... Egypt... I dunno, the military owns everything in Egypt, don't ask it all to make sense).
Lots of good clear pics would be nice, and someone like Horilka will be around to give a sense of whether its real or humped.
If real... Probably some extra value. These are quite uncommon M44's.
If humped... Still a M44, so condition would determine value.
