I've taken Marks 600dpi scan and converted it to Pro/Engineer models. Attached is a plot. What I don't know, is what any of the actual dimensions are. The model dimensions are in units of pixels/100. Nor do I know any depths.

If Mark is willing to mark-up the pdf with some of the correct values. I'll fix that and post a corrected plot and a set of step files.

EDIT: I noticed I have some of the parts mis-assembled, fix it later. I'm off to bed.
