David:
I was affraid that would be the problem. Oh well… there’s always something new to learn – I guess that’s one reason why I’m attracted to Horology.
As to stepping through the the escape wheel pallet fork one index at a time, the assembly won’t move off of the teeth upon which the fork is initially installed. I can, however, see the amount of drop and lock between those two teeth so I guess I’ll have to go with that. The escape wheel is in good shape and isn’t bent or distorted.
I suppose I’ll be using the old pallet warmer afterall. 
Thanks!
Tom
