I remember now the 1 and 1/2 inch came with an old set of governors and was not the pattern. I remember now I was loaned the original blue prints for the Pickering steam governors including valve and seats which I was allowed to copy. I must of given Dave a copy and then he cast me two valves. I then gave them to John who machined them up and also made the seats. Dave must then have the pattern he made off my drawings for a 1 and 3/4 inch valve. I have just taken a photo of both valves, side by side if it helps.

I’ll contact Dave Ragsdale. Under current restrictions may take a while to get a casting made however...
Thanks for your help Craig
