Utah Micro-gap "trumpet" speakers

I bought an old Sano 2x12" combo on eBay, and I am restoring it. It has to be 50 years old, but in great shape. The speakers are unusual - they have a trumpet shape. They sound good. Should I use them or replace them? If they blow, what are the chances they can be properly reconed? The trumpet shape of the cone is so unusual. Thanks for your opinions.

Those are different!
Not sure who could re-cone those due to the shape and vintage construction.
Well maybe a brainiac that could simply disassemble the speaker and re-wind the voice cable.
Maybe a new spider as well.
Mucho money.
Most speaker paper gets dry and brittle with age, so hitting them with much power will probably destroy them.
If you value the originals enough to replace them before much use and you don't mind spending some money, buy your favorite guitar speaker x 2
And rock on.

The biggest danger of running those old speakers is unwinding the vloice coil. They used a shellac like glue in the 60s and it gets dry and cracks.
I wouldn't run them myself. New speakers are available in so many types that I won't risk any of my vintage speakers.
