LHJ = Bashan
Something weird in there. The barrel don't looks like typical water-cooled CG250 ...
71 What's that? The most common water cooled uses 67/69/70 (16mm pin) piston ...
F = Air-cooled in theory

As u said it's some oddball
171FMM maybe a lie... Measure it 1st. Barrel: height * width as http://www.mtctg.com/category.php?cid=5 | Piston: the Ø, pin Ø , compression height
If matches a common 16mm pin model, u're saved from hellhole ...

If you can't find the gasket you might have to go the route of a universal sheet gasket you cut to match. Metal shimstock possibly.. Not sure on this one.
