Kriegsmarine Y-strap. Messed with?

[Frans H.]

Yesterday this KM Y-strap arrived. I noticed immediately that not all metal parts are from aluminium. Two metal parts are made of steel and one of aluminium. On my other KM Y-strap all metal parts are made of aluminium.

So, maybe I am a little bit paranoid, but could it be that these 2 metal parts are added later to complete? I am thinking that those 2 metal parts made of steel are not periode added, but later. So, not original to the KM Y-strap.

What do you guys think of this?

On heer combat ystraps this is common, i have 1940 dated ystraps that are all alumiunim, a pair of mized steel and alumiunium and also full steel ones.

On the 39 dated i have seen only alu.

May i see the KM stamp on yours? also, are they dated?

I have seen many of LW straps (that are only makermarked) with a fake KM stamp added to inscrease the value.
