I asked about the tag and he replied that he has been collecting 50 years with 135 cast iron Jensens. Anyone met him before?

Looks like a made up 50 by someone who got hold of a #50 base casting and flywheel and fabricated the rest of it.

  • Connecting rod is not Jensen.
  • The cylinder even looks like it could be home machinist built.
  • Water pump is definitely not Jensen.
  • Block flange/governor valve is aluminum (should be nickel plated brass)
  • Metal blocks supporting the cylinder also look like aluminum (should be nickel plated brass)
  • Round head phillips screw was likely never used as a crank pin by Jensen.
  • Governor gimbal looks correct (from what I can see of it)
  • I like the addition of a crosshead guide oil cup.
  • Clever adaptation using two #20 boilers.


Please correct me if any of you know different.

Yep I spotted some of those mods/repairs, still a neat piece though! Would love to see his 134 other engines…

This is interesting!   I’d be figuring out a way to make the water pump to both boilers!  ;D

I'd be happy with a #50 with one boiler  ;D
