It's been ages, seemingly, since Dave Taylor has been around here. Since the terrible fires, maybe? Or am I having a Senior Moment? I'll not forget when Dave and lovely bride came to Maine, and Dave's comment that blew me away. "Trees; you have trees up here."
There was also a David Taylor on POA, but I don't think "David" was from Texas.
I sold it to an A&P school. They told me it was for teaching students how to wrench on airplanes, but your version might explain why they were the highest bidder!
