Retained both gear boxes too? How will that work?

Certainly is! Beautifully made little beasts, in 125/150/175.
But why double up on engines and a spare unit gearbox (except because you can) when you could have an LC4, 350 inline twin in S7/8 Sunbeam style? Elegant or what? Very sought after in these parts, albeit a bit complex and not an easy thing to keep fettled.
Or you could settle for the Z22C 175cc with decent (proper pump) lubrication, casting quality to die for, lights that work! I built one up from 3 crates of bits about 10 years back as a winter amusement project and 'sister' babe for my LE Velocette, and I loved it - but sadly I couldn't ride it owing to excess height, girth and lack of flex in knees and ankles,  . . . so I passed it on to a shorter smaller person who loves it still!

Must admit I've never heard of the LC4 model, and it sounds interesting. At the moment I have two 500 BSA twins both 1951, both black, one across the frame and the other in-line.
The particular brown and tan colour scheme of the hordes of post-war Motobecanes etc at French meets makes me feel physically nauseous after a while.
