Hello Lex. I had hoped to get you started by offering you the callipers from the top of the list, but so far have been unable to put my hand on them (too many hidey- holes). I will probably have other bits and bobs, but not always with the broad arrow, such as a 1/2” belly brace.
I live in Maidstone, Kent, so not sure how best to get stuff to you, but if you seriously want to fill the box I’m sure there’s a way.
Regards, Steve.
