249cc John Morris 2 stroke engine
John Morris engines are not common, they were fitted to one model each of Rex Acme and Hobart, an 'MB' (as yet unknown) and even advertised their own bike under the name of 'Morris' (see below). Imagine my surprise, about 6 years back, browsing ebay, to come across the exact engine. The owner hadn't a clue what it was, and I was the only bidder. The engine doesn't even have the makers name in the magneto chain cover, but 'Mark IX'. The engine to the right is one I spotted in a frame and forks at Beaulieu about 25 years back, but couldn't afford at the time (more later).
