OK will cut windows to your specification, at the last time I looked.
Rex, doing some quick searches it seems Mac shops were finished more than 15 years ago. No idea about OK. Seems many of these products were under the radar, a real shame. My Father had a small O scale product line and advertising in OGR was a necessary expense. Pre internet businesses had it tougher.
I only recently heard of MAC, Kasiner, OK.
