Hi Guys, My latest purchase, a spring motor that was on eBay. (I think you may have all seen it, it had a Bettini carriage) just arrived and I'm really pleased! The top casting has a serial number of 6750 which makes it very early I believe. The mandrel is missing (so I'll be looking for one) I'll also need an early carriage for this machine and a crank. So if you can help please drop me a note. The machine also has a number of other anomalies some of which I am not 100% sure about. I'll take some pictures later today and then post them somewhere for you to see! Anyone able to tell be how early the 6750 may have been, I believe that it is the Class M upper works. Cheers, mario
