There early guns are nothing special but the later stuff certainly is quite amazing. They did try selling the business a little while ago but go no takers. To specialised and apparently the majority of their work is bought by half a dozen collectors who are all getting quite old and therefore they don't really have a wide customer base, which makes the business difficult to sell.
There have been a few super grade gun makers who have retired recently and couldn't sell their business for the same reasons, such as Bertuzzi in Italy.

Waidmannsheil.
