Hi Doug,
If you go to the wesite that derjager posted above and scroll down you'll see an example of the pin.
There is also another Swedish pin below it.
The two things that identify my pin are:

1. The pin is soldered to a round base and the base attached to the back of the tinnie. The pin on an original is soldered directly to the back of the tinnie (no round base.
(You can see this in the example on the above site. The pin directly below it although a different style pin better illustrates the pin directly soldered to the back.

2. The original is maker marked. Mine isn't maker marked.

I will say it is an excellent repro. When I hold it in hand it really does look original...a real fooler.

Regards,
Ed
