Interesting engine case mark on a K6 750
« on: December 27, 2016, 04:04:45 AM »
  Noticed this hand written mark on the backside of the upper and lower engine cases on a K6 750 engine I am working with. Don't recall seeing this on any others, have to check some other spares sometime. Pretty sure the engine had never been removed or worked on before. The marks are a S and a P with that square box that looks like a Japanese symbol maybe ??
