Altec 291 "as is" HELP

Pair for sale sorta near me and can tell seller knows nothing about speakers. I am under the impression worst case they would need 'frams. Or could these be totally shot? Best case they fire right up of course. Wear looks typical and nothing brutal. Plan to do the GPA 'frams but wanted to check with the gurus here before I get serious about them. Thanks in advance.
 
My 291s have 6 allen screws, 288s have 4, and the 800s have 3 screws. The 288 and 291 are way bigger and heavier than the 800s. My 291s are Alnico, so maybe that's the difference for number of screws.
