Hi everyone,
I have a very technical question about the HJ leistungsabzeichen made by AD Schwerdt. Some collectors claim that these badges are made of cupal. Our old friend Jo Rivett once said they are just made from silver washed messing. Now I have made some little study about them and I came to the following conclusions:
Cupal was an a replace material that mainly came into use during the War. So that doesn’t fit with the rather early type of this non-RZM marked badge?
Tombak (a coper alloy like messing) weights about the double of Cupal. When I weight M1/101 marked leistingsabzeichens they weight around 9,25 gram, the AD Schwerdts around 7.30 gram but they are thinner executed (material thickness 2.25mm (M1/101) versus 1.8mm (Schwerdt)). So they don’t weight the half of the M1/101.
I also don’t see any kind of sandwich structure on the edges of the badge normally visible with Cupal?
So I came to the conclusion that Jo has right and these badges are made of a copper alloy and not from Cupal. However, rather think of Tombak (a more reddish colored alloy) then messing (yellow colored alloy) like visible on the worn off lettering on the front.
Remarks and conclusions?
