    I just bought this Cab with a Super PA Plexi Head. All Speakers are working fine as well as the head.
    T1221 Celestion Speakers
    Date code 3x 28HA + 1x 16HA
    I can read on the cone 102 003 on 3 of them, I couldn't read the last one (believe to be re-cone)

    What do you think about it? does-it look all original?
    Is-it from end of 1967, 1968 or earlier?
    Is-it a 1960, 1982, 1935 or other?

    Late 68 (speakers are Aug 68), model 1960B. Pics aren't very good but apart from the big white 9" logo on the front and the castors, it looks all original to me from what I can see. Grill is in nice condition.

    What are the stickers on the speakers?

    As per the 1971 Marshall catalog, a 1960 cabinet will be a 100 watt cabinet thus equipped with four 25 watt speakers. Thus it would contain G12M25s.

    If it were a 1982 cabinet, then its rating would be 120 watts and contain four 30 watt speakers, G12H30s.

    And if it was a 1935 cabinet, then it would be equipped with the 55 Hz versions of the G12M25.

    That catalog establishes no difference between the three cabinet designs, just the speakers that were installed in them at the factory.


    At some point in later years, the stock speakers that came in the cabinets changed in some cases. For example by the late 70s a 1960 shipped with four G12T75s instead of G12M25s.

    Not quite.
    The first 1935 Bass cabs (67) had Goodmans speakers. They then had the Greenback G12M55 25 speakers, then cream then black back varieties, the 65s came before the 75s.
    Same with the 1960 cabs, started with G12M20 75Hz, then G12M25s etc
    I won’t rattle on too much as Bygone Tones charts all this on his website.

    The black sticker on the frames I was wandering about. Whatever that place was in 1968, guitar shop maybe, according to google it is now a restaurant called 'detour'. Sign of the times if ever there was one lol.

    I was referring only to the information from the 1971 catalog. It's the earliest Marshall original information that I have to work with.

    Yes those old catalogues are really useful. Have you had a look at Bygone’s site?

    No worries. They'd already made significant speaker, cab design, cloth and logo changes by 1971. I've got a 67 stack and one 68 bottom here. They all have the plywood strip that runs from side to side at the bottom of the baffle board. 69 went to triangular support pieces in the baffle bottom corners. By 1971, Marshall had deleted those baffle support pieces on the bottom (a mistake IMO).

    The Doyle books are what you need. Most of the early catalogues are in them. The newer one also has a nice Park catalogue in it. Great reference books.

    The Doyle book with its catalogs is a great baseline.....but that reference is totally superseded by Bygone Tones, neikeil, TAZIN and a few others here. These guys are the foremost Marshall/Celestion experts ON THE PLANET wether they admit it or not.

    ‘I’ve owned, collected, gigged, restored, repaired and studied late 60s through 80s Marshalls and Celestions for decades now. Yet I consider myself an enthusiast, not an expert. Maybe I can be considered advanced regionally at best, and that doesn’t mean much since the internet. Compared to some guys here, I am only an egg.
