41/42 Luger with Black grips

[blueeagle289]

I have a Mauser 41/42 with matching numbers and black grips - which appear to be original, according to descriptions by a Luger expert.
Who has exact knowledge of the mfg of these guns by Mauser in that period and whether they document production of this weapon as a Black
Widow that is not a "byf" stamped item. The grips are perfect and smooth, with the inside screw hole into which the grip screw fits.

Charles Kenyon indicated that these conditions may indicate that the grips are original ......... does anyone else have some info about that??

Thanks, Ben Carter
