Yes, that would be wonderful!
I am going to look for any of the Wall plans available, and then clean them up like I did these 4 cyl plans.
Ask him if he would be willing to lend the plans for 2 weeks. I promise to handle them carefully, and return them promptly.
(If you can get a good copy off them, that would be great, but if not, I would rather borrow them. )
I myself am very bad at computers, BUT, I am close friends with a guy at the local blueprint place, and he is the one who actually cleans up my prints. I take him a LOT of prints, as I work on a lot of antique cars, and some of them are nearly unreadable. He works with them on the computer to clean them up, then prints me a sample copy to see how they look, and then I tell him to go ahead, or just skip it. But I have only had 1 drawing in the last 5 years that he could not clean up to look like new. (I asked him once if the work for me wasn't a PITA, and his response was he would rather do work on my prints than any of the regular stuff they do there, because my prints are always really interesting.) He is exceptionally skilled, and unlike the gum-chewing teenage girls at most copy places, he is actually motivated to do a good job, as he loves old machinery.
Wait until you get your copies of the Wall plans, and you will see what I mean.
I would, of course, send both you and him a fresh copy of the cleaned-up plans, along with getting the originals back.
Kind regards;
Bill
