Are they a genuine Swindens or just a Wiltshire knockoff?
I know it's considered bad form on here to be picky about spelling but you might find more information on the web if you get the manufacturer's name correct. Knowing the size of them would be helpful too
Yup sorry clearing out my dads old workshop so don’t have them right here in front of me, I’m told the swindens 250409 if that means anything to anyone
