Perhaps your spkr came from a baby grand (table top) set rather than a console. The important issues are the output transformer, does it have 4 or 5 wires ? If it has 5 wires it would be for a push/pull output stage which wouldn't give you a good impedance match for your single 47. You want to see 4 wires.
And the other is is the field coil good? If not then you will need to rewind it or find a spkr w/a good one.
Lead length isn't much of a problem, at 80+yrs old it would hurt to replace them anyway.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
