German standard hardware

[bobm4360]

Is there a source for German wartime hardware or working drawings of same? I'm looking for the following:

Augbolzen LgN 15 932, 5 x 35 (eyebolt similar to AN42)
Gabelbolzen LgN 15 932, 3.5 x 33.5 (clevis bolt with similar profile to eyebolt)

I know the spec numbers are the same, but that's what it says in several parts lists.

Thanks,
Bob
