If it actually said Bruchet on the opening lever, that would be an odd bird-they only marked them like that for a few years.
14.5 for a used Darne is a bit off the hook, JMHO, but, I've been out of it for a while-I never got that much for a new one, for what it's worth.
If a Darne doesn't fit, don't buy it. Most of them, don't.

Best,
