Stour-boy Posted November 6, 2012 Report Share Posted November 6, 2012 Hi Guys, Does anyone know what the threads are on older french guns ? They certainly are not metric. S.B. Quote Link to comment Share on other sites More sharing options...
Salopian Posted November 6, 2012 Report Share Posted November 6, 2012 Stour-boy, The problem with gunmakers is that they used anything to hand at the time of manufacture. You do need to remember that metric can be various metric pitches. If the gun ever had a sniff of Birmingham it could be a number of threads from bsf, ba, bc etc. Measure the diameter if it is a metric size it will be a metric thread, if it is an inch fractional size it will be a british thread. Once you have the diameter and thread pitch you should be able to sort it out using 'Google / thread sizes' Quote Link to comment Share on other sites More sharing options...

Stour-boy Posted November 7, 2012 Author Report Share Posted November 7, 2012 Hi BJ, the gun is a 16 bore sliding breech copy of a Darne made by Zavarotti Freres which closed in 1968, The gun was probably ,made between 1910 and 1940 ish in St Etienne .

Bazooka Joe Posted November 7, 2012 Report Share Posted November 7, 2012 You do need to remember that metric can be various metric pitches Casting my mind back I can remember a reference to "French metric" could be wrong ? Unless you can measure the Dia"/Pitch you'll probably never know for sure, if there's a Toolroom/Engineering place not far from you it could be worth a visit, failing that just convert them to metric yourself.
