The woofer look to be original, but for some reason yours were not painted.
That midrange replacement looks like a nasty cheap driver. That is not uncommon as a lot of those older horn speakers have developed problems with their diaphragms. Quality replacement are available from sources like Great Plains Audio, but idiots throw the drivers away and bung in any old thing.
I do not see a good picture of the tweeter.
The crossover looks to be pretty original with those large Hammond chokes.
We live within four miles or so, so I could measure those speakers and see if they are any good.
