More stuff, this time AT weapons:
The 37mm AT guns (both of them, the current OOB has only one) were not really used in AT role after 1945. No source I have seen mentions them as AT assets in the 1950s. A possible exception is the Pak 35/36 with Stielgranate 41 HEAT grenade. However, currently it is not modeled in the game at all. The 37mm guns were kept in storage for infantry gun use until much later, though.
The 45mm AT guns were officially retired from AT use in 1960, but kept for infantry gun use much longer.
I have not seen any evidence that 45mm APCR ammo was ever used by the Finnish army. Almost none was captured during WW2. In the OOB it is provided since 1950. At that time APCR (PzGr. 40) ammunition was purchased for the 75mm AT gun (7.5 cm Pak 40) from West German surplus (there were still many leftover WW2 ammo stocks in Germany), but it's unlikely that they had significant numbers of (captured) 45mm APCR ammo. Soviet Union on the other hand did not sell ammunition or spare parts for weapons captured from them (they were quite adamant on that).
The 75 PstK/97-38 (7.5 cm Pak 97/38) was used in the 1950s and even beyond as an AT gun. Finally retired from reserves in the early 1990s, at the same time as the 75 K/40 (7.5 cm Pak 40).

95 S 58-61M RCL (weapon 047) should be weapon class 22 (Multi-Charge HEAT). The grenade has a steel "nose" designed to defeat light / 1st gen ERA (even if it's not technically "Multi-Charge"). Official name of the grenade is "Okr 95".
The TOW missiles and launcher names are fudged. TOW missiles used by the Finnish army have been I-TOW/BGM-71C (PstOhj 83), TOW-2/BGM-71D (PstOhj 83M), TOW-2A/BGM-71E (PstOhj 83MA) and TOW-2B/BGM-71F (PstOhj 83MB). The latter two are still in service.

A side note about the I-TOW/BGM-71C and TOW-2/BGM-71D: it appears that these missiles are weapon class 21 (Multi-Charge ATGM) in the USA, USMC and Finnish OOB, and probably others as well. However, to my knowledge the standoff probe is not designed to defeat ERA and I have not seen such a claim in any source. The TOW missiles have a relatively low kinetic energy and it's doubtful if a passive probe or "nose" could detonate an ERA block in any case. If someone has a source that claims the passive standoff probe to have ERA defeating capability, I would be very interested to see it.
