Russian ordnance in chinese service

[Commissar Piotr]

A Russian mortar BM obr. 37 (82mm) may fire ONCE before/after disassembling/assembling the weapon if the scenario is set after 1941.
Two questions about this:

1. I assume that means it is not possible to do this in 1941 but only in scenarios set 1942 and onwards?
2. What about other nationalities using the same mortar after 1941, can they also use this ability, for example the chinese?

1. Correct.
2. Not unless the specific Ordnance Note allows it
