Ok well its sorted, using a small cylinder drain cock from a 5" loco I turned up an adaptor using 6nn hex bar threaded one end for the boiler at M5 and the inset to match the draincock 5/32 x 40tpi altered the offset on the handle and silver soldered this in place.

Tested and all works fine, made up the new pipework and steam tested it.. this gives very nice slow running control when useing one of my regulator sets
