I have been offered this I believe 1944 Walther PP in a trade deal, it is a nice old gun but I noticed there are a lot of variations on these guns and prices vary a lot.Any information would be appreciated
For prices, go to GB and look up "closed auctions". Better gauge on "value".
As a general rule, PPs go for less than PPKs. Special things about the gun may change that (i.e. waffenamts, duralum, grips, numbered mags, type of mag, etc) and refinished vs. original also impacts 'value".
Being a matching number late war with appearingly original ersatz grips, nothing about the pictures strikes me as being over the general average of "previously sold" values, and the sight, as mentioned, may decrease the value slightly.
