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

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

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

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.

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