New unmarked EK1

[Motorhead]

Hi@all,I got this one in today-3 piece construction,magnetic core.But who's the maker? First I thought it's a "Zimmermann",but the core(especially the date) doesn't match.2nd thought was L/19(needle and hinge matching perfectly) but I've never seen a L/19 with magnetic core....So if you've got an idea,let me know.

we discussed these crosses several times. to me these are very early deumer crosses. (and not großmann!)
