The bell cover and basket says "Jensen" to me (EDIT: or perhaps Utah)... but I don't recognize the specific model and (obviously) there's no label on the back of the bell cover. Perhaps an OEM version of a Jensen. Do either of the numbers stamped on the rim of the basket or on the cone start with "220"? That is Jensen's EIA identifier code. http://www.webervst.com/codes.html
I'm not the current owner of this beautiful speaker + cabinet. So i dont have it on hand to check the EIA code. When i first seen it, i was thinking the cab resembled a Jensen Imperial Reproducer.
Mostly because the enclosures and the speaker drivers were often sold separately.
Take a look at the 1950s general catalogs at www.radioshackcatalogs.com and you'll see...
I bet that's one warm, sweet-sounding little cab for mono stuff. There are very-few modern speakers out there that can make mono stuff sound wonderful, and these old alnico drivers do it very-well (since that's what they were designed to play).
