I've just found a bassman cab on my local craigslist. Seller says it's a 1x10, but the model number seems to be T-15, so I'm not sure if that's true.
Here's the ad with pictures:

The serial # is F059493. I've looked on the Fender site, but can't find any in this format.
Any Fender gurus here have any idea on the date of this thing?
