MP41 is PNP.

However when (and if) you need it, I could find out for you from the Russian forum if I could get a larger cheaper shipping from them, though I do not believe you will need many.

Also again, when (and if) you need any we will first see what those are (voltage/frequency/beta) and then I have a Soviet catalog from 80s at home, we will find out the closest substitute and then will try to procure it.

Another option is - there are authentic local transistors also sold on eBay, many-many Ge transistors of all kinds, even the tophat-pinch tops.
