Help identifying 10" vintage speaker

Hello everyone,

I have a 10" speaker that I'm trying to identify. I was told that it's the original Fender speaker from a 1967 Princeton Reverb that was reconed in the 1970s. However, I've been unable to find photos of a Princeton with a similar looking speaker. There's no Fender sticker on the back. Instead, there is a sticker for "Super Music Products". I think that leaves two possibilities:

1. The most likely explanation is that it's not a Fender speaker. It's an old speaker from a now defunct company called Super Music Products.
2. It's a Fender speaker reconed by Super Music Products, who replaced the label with their own sticker.

Does this resemble any original Princeton speakers that you've seen?

 

Thanks for the responses so far. I can't see any code numbers on the speaker basket, unfortunately.
The observation about the paper gasket on the back of the rim is interesting. There is also an [thicker] paper gasket on the front, but perhaps it was designed to support both mounting options. There are some adhesive globs on the back paper gasket [visible in the photo] but these could be from handling the speaker with sticky fingers during the reconing.

 

The resistive impedance measures 6.4 ohms, so it's in the 8 ohm ballpark.

 

Thanks schmee, I think that picture confirms that it's a CTS. I haven't actually played through it yet but I'll try it later tonight. I'll also try to carefully remove the paper on the basket rim and report back.

 

I managed to scrape off most of the SMP sticker, which revealed the following stamped info:

PA 10
MEXICO
137 7813

The 137 confirms it's a CTS and is probably a PA speaker like schmee suggested. The 7813 indicates that it was manufactured in the 13th week of 1978, right?
