That looks to be the Brunel version of the Coomber rotary engine.

There is a construction series in EIM which commenced October 1990, Vol 12 No. 5 by Tubal Cain.

Just watched the end of that one....three bids in the last 10 minutes pushed the final price up to 486 pounds sterling. Nice engine but seems a bit pricey...obviously not for the winning bidder though.

Elmer's #43 is a Comber.  Finally got mine working well for NAMES show.

The inventor of the engine was W. A. Coomber, if memory serves.  I believe Verburg's "Comber" was a misspelling that has been relentlessly propagated by the Usonians.
