incremental success:
1. the Radio Shack (RS) jumper fit the Lowe's terminal block
2. I stripped a length of bare wire and made my own jumper until the second RS jumper arrives in-store
3. I wired everything without a hitch
4. The Red Baron pylon worked as before
I have some guests coming over next week and bringing 4 kids, so I'd like to get all other switches and accessories connected and operational tomorrow
