Marshall cab Q.

[straycat]

Found a Marshall cab that has me stumped.
Looks narrower than a normal cab not any taller.
Loaded with 4 Celestion GT-12 100 watt speakers marked Ipswich England.
Black tolex, black grill cloth.
One round plated input for the cable.No model plate or numbers anywhere on the cab.
Slant cab.
I had thought mode four cab at first but those are taller cabs.
Interesting thing it has the back board that is open at the bottom so the cab is ported to some extent.
Never saw one like this and wasn't sure if its an original out of production cab or a modded cab.
Info from you Marshall geeks is what I need.

An old Valvestate cab?

Not sure Toe were they ported like this? Been looking at pics trying to find out something.The whole no marking thing has me wondering.

An old Valvestate cab?

my 8100 cab(whatever the model # was 8412 something) had 4 30 watt speakers, probably not valvestate.

Hmm. I don't remember any being ported, but I would think that could be a home made job.

Could very well be done after the fact. It has a piece of trim on the back panel and looks original.
I hate to end up buying a piece of junk just for the speakers.Need to pull the back off and see just what the cab is made of.

After closer inspection the cab in Q looks to be a particle board cab of newer mfg so I passed.
