Great! thats exactly what you want to see on these types of rings... Some will say postwar as it looks like a 'rotary' tool. Well those tools have been around way before WW2!

Otherwise its tools like above,,the simple 'gravers' ,and occasionally a trick wheel type.... Almost all these rings either a silver alloy or brass type that are quite soft!

Thanks for posting... Getting photos like this can sometimes be very hard to get.. - Members your forum you can always add on photos when you'd like..
