    Thank you very much .... I found it very strange to have never seen one like it.

    I think that it is a 1959S model (please check tho'!) these were made late 80's - often in black/green levant head cabs. The rounded front panel corners on the head cab were quite distinctive.

    "S" would represent small in a small head and cab and the back would have a bunch of different writing, disclosers etc, maybe even a barcode.
    Also a sticker would indicate that on the top of the chassis.

    I have the 2204S but I've never seen a 1959S before. Now I will spend the next few years searching for one. Thanks Neikeel, thanks a lot. Lol.

    Four inputs and four speaker outputs and six knobs makes it a 1959. That the back panel includes "MARK II" on it means 1974 or later. "Super Lead 100w" also is definitively for a 1959. That it has the coin type impedance selector means it's made not before 1979. That it's a 1987 production amp means it's a 1959 reissue, which specific version I don't know.

    I've never known a reissue to have that plain back panel without all the disclaimers and other writing...however I could be wrong.:shrug:

    That kind of puzzles me, too. Looks like a regular '70s back panel. I guess we'd have to get a look inside the chassis.

    I've seen that the extra warning labels are waterslide decals that were applied after the panels were made. They can be removed without a lot of effort,
    and with the right solvent, any additional printing or silk screening could be removed as well, leaving no trace on the panel. That'd make it look more vintage correct.

    So, what 1980s era 1959 reissues would there have been?

    As neikeel said, it's 1959S. They all had a polarity switch and four speaker jacks. There was also a 1987S.

    The early 1959SLP, 1987X and JTM45 reissues also had the rounded control panel cutouts.

    Looks like a good explanation to me. I didn't know they had done that. Like to see back panel of the advertised one and inside of the OP's. I don't see a polarity switch though but may have been on the 1959S ?

    All UK/Europe marshall's don't have the polarity switch and only feature two speaker jacks on the back.
    The 50 watt S's were in small headboxes but could be recognised by the large corner curves cut out for the control panel.
