Thanks, but considering that steel and gunmaking centers propagated technology by sharing technology, the find might well be assumed. The relationship between gunmaking centers is much more stringent that we might want to admit. Always remember Belgian labour was cheap and they had embraced mechanization early on making the center a choice of sourcing. I was hoping Peter might find the original Belgian patent, but then again I haven't searched myself( GB000190615236A - Belgium Patent date - July 11th, 1905 ), and it would be a few years earlier. But, um I'm still not convinced the sourced Sauer & the patent are one in the same. But we shall see.

Kind Regards,
