Title says it all. I came across a handleful of these and am looking for info about them. I can't find any info about the manufacturer, they don't seem to have an internet presence. Thanks in advance
I have an operator's manual in hand right now. These were about $5,000 new 25 years ago. When I searched a few years ago, I could not find anything either. You can contact me at sales at raptor resins dot com.
After writing that first post, I also managed to stumble across the Hakuto Denko HA-151B. It looks like an almost identical unit to the PGS-151, and it is currently available, so I've contacted them for more info. A manual for that one is available here: [URL unfurl="true"]http://nadascientific.com/media/PDF/HD/N600-HA151B_Manual.pdf[/url]
