Pith, here is a example of one I sent off for rewind. The primary (top wind) was open. I believe your coil will have a lot less winds on it making it easier. This is not the same coil as yours but an example of what your going to see. You will be unwinding the top section of yours if after inspection and you can't repair it (broken wire going to lug). Count the number of turns and note the direction of winding (both important). When you remove the assembly confirm that it is open and also measure the other 4 connections (the secondary). Should be low resistance between all four of it's connections. Secondaries seldom seem to go bad. Your proceedure outlined above looks fine to me and yes the wire that winds around the coil form that is the primary (the one on top) is broken so there is no low resistance measurement between the plate of the RF tube through the fine wire on the coil to another connection on coil. Wire size and number of turns may be answered by someone else.
