I worked there for a little while. Steve is correct. The bread and butter for MWK was the HeNe sales and air cooled argon sales. We would occasionally sell the larger frame SP heads and PSUs, but diodes and chinese lasers killed off a lot of sales. Mike Kenny, last I heard was just selling off the bits of stuff that he had available on eBay. All of the old crew has disappeared... Mike, Ernie, Martin......
