Robert is correct, I have Rapide engine #38 which originally went to Malta. It was crashed there and shipped to Scotland in the early fifties. Sometime shortly after arrival in Scotland the engine was put into a C Comet rolling chassis. The original upper and lower frame members must have been repairable or perhaps unharmed as they are now in use on a bike in Sweden and a bike in Scotland.
The bike was used for many years in Scotland, then went onto England, then was sold by Verralls into Australia where is was ridden for a decade or so. I bought it in 2004 and had it ocean shipped from Australia to me here in Vancouver, Canada. I've ridden it about 25,000 miles to date and have enjoyed it immensely.
Somewhere in an older MPH there is a 1947? photo of a man in Sailor garb, in Malta, sitting astride a new looking B Rapide. I recall that the info under the photo states that the B Rapide is one of only two B Rapides that were sent to Malta.
