Hello I would like to report on the 22mm "Ebay" Terry's clip.
they are very similar. I belive as well the original were black. on the back of the broken one i found trace of black paint.
The Ebay one has the same distance between holes and the same holding diameter.
The wings have the same shape, and the platform as well.
The only difference are the rivets, the new one has only one.
Sorry for the rivets counters! but with the starting handle in place you should not see it! ;-)
