Got quite a few of these in the CMBA (Classic Motor Boat Association
http://www.cmba-uk.com/ ) & I love the ali ones, for some reason the plastic one's don't do it for me although you get the option of the Essex V6 version which, whilst only a little faster, sounds a lot better!
I am looking for a straight tin one myself to add to the collection, pretty boat in my eyes.
Larby, I enjoyed reading the thread on the Revenger rebuild (well most of it, if you get my drift) - where is it at now?
