Identifying Speakers in a 1966 Super Reverb

[Reader]

I am trying to identify the speakers in a 1966 Fender Super Reverb Amp and I have had no luck Googling for an answer.
The speakers appear to be an original matched set. They are ceramic magnet with the Fender "Special Design" blue labels. The only other marking is "C4-7 66" printed in white on the rim of the basket. This has me stumped since it doesn't seem to include an EIA code. The 66 makes sense since the amp is a 1966 amp.
Can anyone help identifying the speakers?
TIA

A good clear photo would help. We don't need to see all 4. Focus on one and I'll bet you get an answer.

Most of the ones on Reverb.com have Oxfords in them.

Maybe, but I have also seen Jensen ceramics and CTS alnicos in these years.

True , but i said most. Also, the Jensens have a 220 eia code which is usually very visible. Op said they are ceramics.

Let's wait for the pictures. There are some more candidates, like Pyle or Utah. As well as CTS ceramics. Oxford ceramics often carried a paper sticker with a 465xxx number and the speaker type. And the speakers might have been replaced.

Thank everyone for comments.
Attach is a picture of the speaker I ask about. The marking on the rim is all I find and is the same on each of the four speakers.

PS: I cannot upload a picture. I am using advance setting and the paperclip button and following the prompts. Tried several different types of files without luck. I'll keep trying but maybe I need to be a senior member to upload files?


I made the picture file smaller. 1.2MB would not load but 65kB did.

Pretty sure that is an Oxford.

Pretty sure that is an Oxford.

Could be but, if so, wouldn't we expect to find the 465 EIA code printed on the speaker frame?

They often had a paper sticker that fell off. That said, I'm going by looks alone so I could certainly be wrong.

I did a google images search for Oxford speakers and did find many that looked like mine.
Thanks for the clue Dude.
All four of my speakers have the same marking or lack thereof. If they once had additional marking stickers then they all fell off or were all otherwise removed.

The hole pattern in the frame looks like Utah: https://www.ebay.com/itm/UTAH-10-Spe...-/153204811679
My Oxfords have a different frame pattern (no round holes).

[The Dude]

On second glance, I think you are right, Helmholtz. I hadn't noticed the round holes.

137 so CTS?

Often the EIA code is stamped under that blue Fender sticker. If you can carefully peel it back, I bet you find it.
