Some day, before I die, I am going to make a floor lamp from a Mark 25. Like you, Tubs, I don’t throw much away. I have a Mark 25 drive shaft housing that has the casting for water tube retention snapped off. Totally useless part, EXCEPT for a floor lamp….Also, with no pistons, crank, gear set, etc. it would be the first Mark 25 ever that was easy to pick up.
Long live American manufacturing!
