Yes! Thank you Ray!
I intended to check on the mm to inch conversions. I forgot to see if they worked out to something handy. And it's been too long since I knew which wrenches could be interchanged.
Yes, I just got out my steel rulers, lined them up, and checked. I'm sure your are correct, Ray. The 1960's sizes from Reynolds would have been 1 / 2 inch for the smaller size , and 5 / 8 inch for the ever so slightly larger size .
Cheers for that.
