Obtained in the early 70s this KvK 2 . Seller indicated it was 'copper metal' and marked 11 .
I went along with that until I joined here and by comparing and learning over time - that it is not what I was told it was .
It is not marked 11 - it has no 'upstroke' on the 1 . It has 2 stamped in ridges/notches - very similar as seen on reverse of some black wound badges .
After various emails I finally gave in and had removed a mini-area on one inside arm tip to reveal what it is made of ....... appears to be solid tombak with a bronze wash on it .
wikipedia.org/wiki/Tombac
Tombac, as it is spelled in French, or tombak, is a brass alloy with high copper content 70 - 90 % and 5–20% zinc content. Tin, lead or arsenic may be added for colouration .
For the longest time the reddish oxide made it quit convincingly look like a copper core .
As a recent post has shown these tombac KVKs can be unmarked and marked . A lot of work on identifying these makers has taken place since then with different dot patern style -
Dietrich is using the dot pattern method for identification - I tried something different (the Daisy) but since have given up on it .
I once again put it up with new pictures to see if a maker can be determined now or what the 'mark' is in the ribbon ring ... incomplete number or letter ??
To aid with this some data :
5.14 mm thick
Horizontal X vertical : 49.05 X 48.71
23.2 grams
More pictures on request .
Cheers, Douglas
