I found this in with some service literature I bought several years ago. It gives all the spec's on engines from 1910 -1960. This gives bore, stroke, weight, prop size, lube, all clearance spec's, etc. It also gives the price on what each engine sold for. It was printed by Evinrude motors, and is not a reprint, it is 42 pages long. Some of the prices are a real surprise, they were not cheap. Would something like this have any value.
