Years ago I bought the plans for Bruce Satra's O-440 engine. I got both the drawings and the machining instructions to build when I retired. I finally got around to pulling them out and found that the bill of materials was missing. Bruce is long gone now and I have had no luck tiring to find out who now has the rights to the plans to try to get them. Any one have a set of these plans that I can get a copy of the bill of materials from? Please contact me to make arrangements for me to get a copy. Cost etc.
