Hi guys, Sniffing around for some wear and tear parts for the parts box and I was wondering if the mainsprings for 321/861/1861 are the same. I notice that the part number is usually designated as: <calibre> 1208 (e.g. 861 1208), so they're all 1208 but is there a difference for the different cals? Thanks as always, much appreciated! J
I didn't think Cal 321 uses same mainspring as Cal 861. A great question and I was researching this. Maybe someone more knowledgeable can confirm http://www.ofrei.com/page_141.html
320/321 spring is 72203201208 860/861/865/910/911/1861/1863/1866 etc. spring is 72208601208 The 860 mainspring is longer than the 320, and also weaker. Cheers, Al
