Knee knockers.
A T-6 is a knee knocker.
The control stand is so cramped and the engineer's quarters are so small, several times a day I knock the snot out of my knee(s) when swiveling around in the seat to look the other direction. Used to run T-6's pretty often, then they started staying north.
However, here a couple months ago or so, a T-6 was sent down to our terminal on account of all the bigger engines were in use/being shopped.
So, it was back to running a knee knock'n T-6. Actually, I didn't mind... sort of a trip back in time for me. (The smell of the T-6 cabs remind me of the aroma of the cabs on Baldwin VO1000's that I was in back in 1970-1972.)
However, being reunited with a T-6 didn't last long: It went B/O before lunch and out of service! (Governor went out.) To the service track it went, and another job had to loan us an engine out of their consist so we could finish our day.
