Questions About an Old Browning Highpower

[Hard Ball]

I have a FN Browning Hipower which I believe was manufactured by FN before the German invasion of Belgium in June 1940. It is a standard Belgian military model with the adjustable long range sight abd no stock lug.
The markings are correect for a Belgian army pistol, however German Waffenmat test and acceptance marks have been added, Is there a source which gives production date versus serial numbers for early FN Highpowers?
Second, the pistol came with one spare magazine. Both original magazines work perfectly, however when I have tried to pick up additional magazines I find that they are to large to slip into the magazine well. I have tried magazines from two other FN Highpowers made at the same time and they worked fine. Does anyone know of a design change that would account for this?

Try this site first www.browning.com/services/dategun/guns/highpowr.htm It'll allow you to date your pistol to 1957. If it's an earlier model I'd email Browning directly.

Thanks Tecolote:
I know that the pistol was produced around 1940 because of the German military acceptance marks which were added some time after the pistol went down the FN production line. It has an interesting history. It was used by both sides during World War Two.

Hardball,
In 1940 the Finnish Air Force purchased approximately 3,000 FN Browning Hi-Power pistols.
The main serial number range block for these pistols is 11,000 to 15,000.
Hope this can help.
