Are they collectable?
I know there are completists vying for the full set of "Machinery", the machinists bible, The earliest editions fetch hundreds of dollars

Yes they are collectable and very valuable to vintage electronics restorers.

Data books on obsolete components are worth their weight in gold to them.

Basically yes, you could reuse the wire you take off and rewind it in parallel, so you have 2 parallel 1500 turn windings to maintain the higher current load from the lower voltage requirement (to keep the same wattage).
