Nice close-up pics, Thanks.
I've never seen one with the wide 'loading tray' type of extractor,,nor the coil spring underneath, or side safety.
Nice looking rifles.
Is it Post WW2 proofed?,,looks like it on the right side but can't quite make it out.

The ones I've had only have/had a half cock safety on the striker. A long flat-leaf spring powers the trigger/sear underneath.
They've all been pre-WW2 made guns. I was never sure if they even made them after WW2.
Bolt about the same w/the separate small firing pin in the head. Same simple disassembly by unscrewing the rear half from the bolt body.
The pre-War extractors have a very thin arm extending back in the sear spring channel and up under the bolt head w/a hook shape.
The extractor drops free of the gun once the bolt is removed on the ones I had,,,and probably the reason a good many of those are found with the extractor missing!

That M/S type bolt handle is a very nice touch.
