I'm clearing out the extras and this is on the list. It's got the same CTS 15" as B-15 of the later '60's including my '67 and makes a perfect mate to a low wattage tube amp. It has a wee bit deeper bass than a vintage B-15 cab and is 4 ohms. At some point, it lost the tuck n roll but kept the fluffy vinyl.
I'm 5' 11" 155lbs with a bad right shoulder and the cab isn't too hard to move or load into a sedan's back seat thanks to casters and some well placed handles.
Full disclosure: the bottom speaker has a very slight buzz at high volumes. I'm talking about volume that will hurt your ears if you get in close to listen to it. It still functions normally but I haven't opened it up and gone on rattle patrol yet, hence the price. At worst, a "new" old CTS 15" will run $50-$75 on eBay.
Still, $100 triples the speaker area of your B-15 rig...
