Mk 2 Sten gun manufacture differences.
Sten gun question again. Just seen a mates collection of deactivated Mk2 Sten guns and noticed the differences between them, some had lugs spot welded to the trigger housing and main receiver housing, some were welded and ground down. Some had trigger guards that were square in shape with the weld done from inside, some had tapered guards that had obvious welds seen from the sides, the guards slightly out of square. Differences of how the stock housing is fixed to the main receiver in that some are spot welded and some are welded and dress, some with just neat finished welds. Would you be able to tell which factory or period they were made. Are there any anorak web sites or books showing these details of the Sten.
