I have heard Reeves no longer supply the drawings due to a disagreement with Ken Swan over priceing. It may be possible to contact Ken through http://www.bmeg.co.uk but I have been trying for a couple of weeks without reply. A point to note is the safety values on Jessie/Bridget do not clear the steam sufficiently as drawn. If anyone as an alternative design then I would be keen to hear from them.
I bought my drawings directly from Ken around 1999 so he has been
selling them direct for at least that long. It would not surprise
me to learn the disagreement over pricing was the percentage of the
Reeves price which made its way back to Ken.
