Fair play on that front - never knew about the FC Sondhi stuff.
I'll keep the replies coming in for sure - have heard of a B3 connection, and was aware of Kippax; I'm a Harrogate lad, so Kippax are on my doorstep - still have one I need lightening - ever since I stopped gym work, 2lb 14 is rather heavy for a wee man!
Was looking at Bairstow's and the handle didn't look very Kippaxy - but who knows, probably made to measure!
