Hi..I took the top casting off..no sign of any milling...did see a small weld repair on a crack..The case has been replated...
So I'm still not certain..probably never will be...Only certain way is if any of you experts visit Oxford ,England...look me up..have some real ale and discuss slots... So...I will get on with what I bought the machine for...thats playing it ...and polishing it !.....Thanks again everyone ..Tony
