J,

The gun is probably an Express which an old Blue Book shows being imported through '89. Listed with ejectors, case colors and iron sights. Last MSRP was $3500.

My gunsmith had one of these in the 80's. I remember the gun as well turned out but very plain. He had milled the rib for Ruger bases I beieve and said it was very well regulated.

As already noted the asking price would buy a Merkel or UGEX. 6K sounds to strong.
