Are these 4310 greys right or wrong?

[mattadork]

I picked up a pair of 4310's and I'm not sure if they are stock or custom. I cannot find a photo of 4310's that look like these so please help me determine if they are correct. I would like to restore them.

Both the tops and bottoms are painted black, so this leads me to believe that this is stock. The grey seems to match other studio grey 4310's pics that I have found online. The serial numbers on the back of the enclosures are 11217 and 11223.

Thanks in advance for help.

It's look like the original drivers but they've been painted black and brown. That midrange might not be the original one in the 4310's buts it still looks to be a jbl driver.

The drivers look right to me just too much sun on the cones and dust covers. The grills?? look like the fabric may have been replaced. They had black aguaplas 123' woofers as well as white way back then. The black cones were typically in the L88 Nova's. I have seen older LE-5-2 look like that as well with a paper dome. Easy way to find out is take out a midrange and a woofer to see what part numbers are on the driver labels. Leave the tweeters alone they are difficult to get out without damaging them and they look right.

Thanks Rob, Hjames and Speakerchef.

Here are some more pics of the driver and mid.


Here are two more weired things about these speakers that may not be right.

1. It looks like the raised baffle has been painted black.

2. There is black electrical tape that is used to complete the "race track" around all speakers.

These two things may not be correct along with the funky grills. Everyone agree?

Is this a early example of 4310 greys or a modified mess?

Yea it looks like someone decided to mess with the cabinets a little. I didn't recognize the mid's were in fact le5-2's which means the dust caps have been replaced.

I have seen early versions with that dust cap. They are also fadded as much as the original cones.
