Ottodog8,
Well, I suppose I will be the one to tell you that you screwed up. The gray pair are reproductions and not very good ones at that. They are of a type that has been seen for many years and this particular maker has faked many types of units. They are almost exclusively cyphered straps and those of other desirable units (Flieger, Luftschiffer, Blitzbundel Telegraphen, Lichtmess Trupps, etc.. I have seen these in some of the most knowledgeable collectors displays, so you are not alone in having been fooled.
The telltale signs are these,
Handsewn (quite small) buttonholes.
Mostly unpiped, but occcasionally with piping.
Exact same material front and back.
Non-period Feldgrau material.
Cyphers are never quite right in design and materials even though these are supposed to be issue straps (these cyphers were very standardized).
Your Dunkelblau pair is fine and are very nice private purchase examples. When in doubt, check with the fine people here before you buy. :?
