This is the first time I've posted to the listserve, hope I'm doing it
correctly. I'd like to buy a proportional divider and have found the Weems and
Plath 4548 online, is this the best one to purchase? I would also like to get a
plexi grid, and see directions for making them in the Guild Handbook of
Scientific Illustration, but was wondering if anyone manufactures these? I'd
appreciate any information.
