I have a large assortment of original Johnson parts lists and operating manuals from the 1920s to 1930s. Appears to be most, if not all, models from that era. Some duplicates, over 100 in all. PM or email with any specific model you might be in need of and I can verify I have it. They are used. Some have greasy fingerprints, notes written on the covers, torn edges, etc. Asking $10 each, postage included in the US, or make me an offer for the lot. Discount available if you want several.
