FLOTTORP ARMOR COATED PROPELLERS Dave Bahnson of www.woodenpropeller.com says that a rumor has been floating around for quite some time that the factory burned down. In an interview with Ole Flottorp's grandson years ago, he clarified that there was no fire but the records were for a biography of Ole Flottorp, but the would-be author died and the records were never retrieved, which is probably one other reason that dates of manufacture based on serial numbers are unknown. The table below is arranged in drawing number order. Locate the drawing number in the left column then read across to locate the aircraft and engine combination the prop was designed to be used on. It may be easier to locate your prop by using the search or find tools of your web browser.
