Szekely aircraft engine SR3
In a Curtis airframe
These are very rare engines today, The owner told me that the term " Dropping a cylinder" came from these. The engines would have entire cylinder and heads fall off in flight
This owner came up with a system to help prevent the cylinders jugs from cracking at the base.
