Hi Irishdiver, the grips you have pictured would be better termed as ,"post war"
The problem is that there are real ones, probably made either in Russia or Germany, made from a Bakelite material? And there are also recent copies of the very same grip, made only with a thermal setting resin,which has little to no strength. So, you are back to the same problem as to how to determine whether or not they are Bakelite. My best method is to tap them together, and listen to/for, the,"clink" rather than the, "thud" Also the fit, and also the weight can be tells as to originality. One last thing, and not written in stone, but the Bakelite grips, ALL of THEM! are made in a heated compression mold and as such are just as finished on the back, an they are on the front? They should be smooth and nearly flawless, just as the mold is. No air bullble and/or rash. So, if it clunks, has rash, is light, and doesn't fit.... I'll let you finish the observation. Best to you, til....lat'r....GT...
BTW, I use these grips on some of my test guns as they stick to your hand like glue... I like that!
