And if that Coles pump casting kit sees a rebirth, you can provide your drawings to the new business!

There's been lots of hot discussion on drawing copyrights, but this brings up the software side. I can't tell what program you're using, but do you have a license from the manufacturer? If not, I'd keep the sales on the down-low. License user agreements for trial or free-version CAD often have clauses protecting this kind of thing from happening.
A little silly and probably over-speculation, but we ran into this with solidworks quite a bit. We were making drawings for a company during a school project, then the company went ahead and used the drawings we made with a school license and took advantage of a trial version to complete the project. It could have been worse than it was, but they certainly keep a close watch on where and how their product is being used.

I have a legal copy of CAD software compatible with Autodesk CAD. I lost my legal access to Autodesk when I retired.
NP317 - that's a neat idea! I don't think it would be a free-bee considering how much work I have put into this drawing - probably 4 full days so far. The work of redrawing in CAD is worth it though- have identified and corrected three significant dimension error. The drawing I have is 1968 so maybe it was an early version: I can't imagine Cole's not updating their drawings once builder's advising them or errors.

Cross drilling holes at an angle can be a real nightmare... unless you also mill the pocket at an angle.
I did this for a set of cylinders and the results were dreamy compared to trying to start a hole on an angled surface.
I used angle blocks against the machined valve surface to set the angle and simply clamped in a vice. From there I knew the distance of the edge of the finished cylinder bore to my hole locations. Milled the pocket, then drilled in one setup. I imagine the same thing could be done with one of these pumps.
