The center pump has had the pressed in cap on top braized, I'm assuming it may have seeped or could have even been an early factory or dealer fix. It also has some wear marks on the feed side drive gear center area which would not reduce pressure or flow. I'd use it as is, on a rider or high end restoration.One plate is perfect, the other has had the locating pin holes enlarged which could be filled and redrilled. I've had most of these since the'70's and they have been stored indoors. I don't want to take the time to sort, identify each and every part, take hundreds of photos so I'm listing these as a lot.
All bodies look very good usable condition as is, no cracks, substantial scars, flaws that would affect pressure or otherwise proper operation. The'41 body has a small shallow indention from the key near the shaft hole which is not in an area to affect pressure or crossover. I have made my living building motors, repairing, restoring Harley-Davidsons since the mid'70's.These parts were never offered for sale, until I listed them here. All parts could be used on high dollar restorations and would be a much better choice than the rather poor and non authentic looking reproductions. These old and funky original components are what make the end result what it is. Do you want the "real deal"? Or is a "repro hack" good enough? The breather gear is a very early model and has not been cleaned up at all. The screen can easily be removed, straightened and a scar around the large hole can be left as is or braized up and polished. Due to the unique nature of these parts and that fact that they are very old and in used condition, they are not returnable.
