K27 flangers

Greetings,

There are a bunch of guys(not me..yet!) that are building live steam K-27 live steam locos. I think a few are regulars here.

A few want to model the flanger and its associated parts, raising/lowering mech, etc. After a bunch of looking around we can't come up with much info. Drawings of course would be great, but good pics would be OK too. We have looked in most of the usual sources, the Mudhens book, Denver Lib. etc... I did find the Priest patent, but that is not a lot of help.

Does one of these still exist? Are the ones on the other NG engine about the same? And the 64 thousand dollare question, do drawings exist?

Thanks!

Paul
