Hey Rich, Thanks for checking. That was very helpful. I was worried about that coupler bar. I guess I'll have to coax the screw around it.
The uncoupling lever is held on in the bracket slots by friction. The two outside slots face forward, the two inside slots face the locomotive. The uncoupling lever can be removed by very carefully sliding the lever ends out of their slots, then moving the bar back to free it from the inside brackets.
It's a little tricky and comes off easier than it goes back on, but it can be done.
