Wow - that’s some complex machining going on. Wonder why Holts are saying 1950’s? (Maybe family legend passed down to the current seller). I agree, it looks too modern. I know Holts photography can make things look better than in daylight, but it is a stunner. I’d fear the balance is a little front-heavy though.

Would love to know more about it. It almost looks too ‘finished’ (good) to be a prototype…
