Problem is that it is impossible to find 4 sub drivers that are similar to the 1850’s on any secondhand marketplaces here. I’ve been looking extensively.

I once had approx 13x, of the "original"  Oberton 18XB1300's.

The originals were great, but then Oberton modified the design, and they started failing.

I sent back most of my units.

I would say, B&C 18DS100 would be one of the best drivers, in the 186 Horn today.

Xmax/Xvar/BL, "maybe" sufficient, to run 186 horns, down to 42hz in pairs.

I think the ones I have a chance to buy are the original 1300’s. So you would recommend getting them to out in 186’s, if I have the chance?

They may work well, but I suggested 18DS100, because it has better Xmax/BL.

186 Horn not natively designed to do 40hz in pairs, so driver with extended Xmax needed, to get cab lower than 48hz in pairs, with SPL.
