LC667

This model is a big sheetdragger, it handles a full 5′x7′ sheet without repositioning. (Yes, sheet metal is more often 4×8 or 5×10.) With support tables and repositioning, you can cut some really big stuff.
First offered around 1984 with 6M control and Spectra Physics 971 laser. Over the years they used 11M, 0M, and 0L controls. Lasers included the Spectra Physics 820, various PRCs, and probably the Fanuc lasers. I’m not sure when the 667 was last offered. I’m guessing 1993 or so.
