Fower A4 / R class Boiler drawing

[fowler10242]

A long shot I know but does anyone have an electronic version of an engineers boiler drawing for an A4 / R class traction engine boiler (pref long box version)? I guess there is a hard copy at the University of Reading but I need an e copy. I am trying to get Polish boiler maker to quote for the repair / replacement of my box / barrel etc. but I need to e-mail them a drawing!

If not, I will try just giving them basic measurements but if you happen to have one sitting on your PC I would be graeful for a copy!

Cheers
