I can't access Gunparts due to a server fault but the Waffenmeister scope is a No32 Mk1 and shows signs of being made withmore attention to detail than the RSM unit.
Note the margins of the block and the screws.
They are miles ahead of the RSM units I have, that were not even remotely well fitted.
Plus they state that the optics are from Japanicon.
I would guess (and this is just a guess) that these are better made.
