Unfortunately I find the patterns for the 6" Devonshire bowdown has the the round flange to the boiler at 2.25" (bare) whereas the drawings call for 2.5" diameter.
Likewise the piston rod gland pattern is 2.7" across the long axis of the oval whereas the drawings call for 3.062".
All castings have been replaced, leaving me with the old stock.
Rather than scrapping I am happy with £20 for a bowdown and £25 for a pair of cylinder glands. 2 blowdowns & 3 sets of glands
The cylinder glands are cored 7/16", are 2.125" long, flange 0.562" thick
