I recently purchased this Pitts project without logs. I'm hoping that someone on this forum knows the plane or maybe knows someone that does. Any info could be helpful. I was told that Ken Brock built it for the original owner, but I have no proof of that. All airframe data plates were removed by a previous owner. I haven't been able to contact the last registered owner in Riverside Ca.View attachment 43317 It is an S1S and currently has a Lycoming 0-360A2D, but I don't know if it is the original engine. The plane has a Christen oil system, but it's not fully plumbed into the engine. For now it has a gravity feed carburetor. It has a Christen wobble pump system which is normally only seen on injected engines or maybe a pressure carb. The individual I purchased it from bought it as is and made no changes. I suspect that it's an older S1 because it has enamel finish on it rather than dope or urethane. The plane was being taken apart for transport when this image was taken.
