All RMLs were imported with Egyptian wood thumbhole stocks and forends.
From the photos and a parts availability standpoint (genuine Maadi parts have never been that plentiful, and are extremely rare these days), my best guess is the stock and PG are questionable. Here's why:
From the photos, the pistol grip looks like either Egyptian or Bulgarian. Maadi grips are made of an almost brittle, unreinforced, semi-gloss polycarbonate-like material (I've had 2 of them crack), with blunt, almost drawn on, checkering. I can't tell from the pic if the checkering is sharp, like on Russian or US made grips. Bulgaria exported black grips, which were much more common, and very similar to the Egyptian grips.
The stock is questionable mainly due to the deep color. Egyptian stocks were more on the light and dark brown side (exactly like the lower handguard) than the common Romanian (and much rarer Russian) reddish and/or mostly brown.
The forend definitely looks Egyptian, with the darker upper handguard.
All that said, digital pics can be deceiving, so I'm only going by what my monitor shows me.
Just my $.02, hope it helps.
