As pointed out by mah, the mystery driver is an SP12D so match is a possibility but less likely since this variant appears to be less common based on web searches.
I'm using this for a mono setup so a match is not a concern for me. Which is good since I've already blown my budget with the purchase of one.
This leaves the question as to the provenance of your speaker. Is it a 3 way with the SP12D as the only woofer? Is there a tweeter, which could be a T35 or T350? Your speaker may be a homemade "one of", as the plans for many of the EV cabs were readily available to DIY'ers back in the day, and parts could easily be mixed and matched. EV actually encouraged a "building block" approach aimed at the DIY community.
It's almost certainly a factory Patrician 800. It looks like the EV cabinet and has the same drivers listed in the image mah posted (i.e. 30W, SP12D, T250 on 8HD horn, T350).
Last night I looked through old issues of the magazine Audio and found that this configuration was for sale for $875 in the August 1964 issue. Given that the 800 was introduced in January 1963 (from an EV ad in Audio, January 1963), I speculate that this is the first version and a second version was produced sometime after. Since I've spent so much time looking into this, I'm considering putting together a history of the Patrician line.
I got Audio PDFs from http://www.americanradiohistory.com/index.htm. This site mostly focuses on vintage radio publications but also has some great information for vintage audio buffs. Most of the issues of Audio are there (published 1947 to 1991).
The Patrician was made well into the late 1970's with the later production going almost entirely to Japan where the SET amp craze was in full swing, while we were still being distracted here in the US by high powered transistor amps. I had been assuming that the Patrician with the 18" woofer was the early version, but I'm not so sure now. I first heard the Patrician at a hi fi show in the early 60's and the 30W was the talk of the show. I have an EV DIY catalog from the early/mid 70's where the 30W is shown along with the SP12C and the SP15A, and there is no 18" woofer at that point. See the hifi lit link here for a couple of early EV catalogs and the Patrician 1V brochure where the 18'" woofer is shown and the Patrician has acquired dual 828 low mids which are double loaded with small horns on the front and a re-entrant horn on the rear. There used to be a lot of information on the EV website's Discontinued Products section, but most of it has disappeared now unfortunately.
Hopefully all of the drivers in your Patrician are functional along with the crossovers. It may be a good idea to replace the capacitors in the crossovers at this point, the T250 diaphragm is unobtainable now as the other posters mention, and the off shore repro replacement diaphragms for the T35/T350 are poor quality. Great Plains in Oklahoma obtained the tooling for making these from EV, but they were having trouble getting good phenolic bases to wind the coils on, or so I've heard.
You don't say if you've tried to listen to your Patrician yet, and a low powered tube amp is highly recommended. The 30W is a thing unto itself, and it's the last driver standing at the 16 Hz C1 on the pedals of a large pipe organ recording. Try Pictures at an Exhibition by Jean Guilou on Dorian CD.
Thank you from the Electro-Voice Brotherhood for your intention not to part out this magnificent speaker!
