    What is the round thing with the 3 rivets holding it in place? My first guess when asked was either something like an arm rest when the stock was new but don’t think so after a google, or something to do with holding the seat base in place?

    Anyone know for sure?

    That’s Bakerloo Line 1972 II Stock and the device is used to unlock the seat for lifting

    I wish they'd reinstall the armrests on the 72 stock. You only realise how useful they are to keep you from sliding around then they're not there! Surely they could have come up with a replacement "vandal proof" design, seeing that all other Underground stock has them?

    True, but then I try to blank those seats out of my mind!

    The ones on the W&C still have armrests I think

    That matter with the 72 stock, given their replacement is due soon, they would not want to be wasting any money on them. Thus, any replacement armrests may fit that criteria?

    for “soon” read 2030-2035.
    They are just about to re-start major work to add wheelchair spaces in each train.

    And the armrests must have been originally removed 15-20 years ago as the major refurbishment was done 25 years ago!

    I thought it was a tamper indicator. If someone has tampered with the seat the yellow bit shows. Most of them are knackered so are ignored. The mechanism for lifting the seat is underneath the cushion overhang, if memory serves.

    Plastic arm rests were removed early 2000s - mainly by locals north of Queens Park!

    Refurbishment was nearly 30 years ago don't know the exact date but from what I've heard the first ones were taken in August 1990 and the final train was completed in April 1995.

    All 72 stock on the Bakerloo had plastic armrests a good few years into this century. Must have been around 2003/2004 they started to take them out.

    When the seats were re-upholsted with the blue seats so I think that was 2004-05.

    Weren't they fitted with the 'dual level' types that were introduced on the Victoria line trains. The idea was that the arm rests had a lower resting place nearer the seat and a higher point at the end. This allowed adjacent passengers to both get somewhere to rest their arms on the same rest.

    I don't know about that. They just looked like normal armrests to me... as shown below.

    No, I distinctly remember the stepped armrests being mentioned in the '60s. It wasn't the '59/62 stock, nor the odds and sods like the '60 stock on which the '67 stock was modelled. I remember all of those on the Central Line which was my local line.
    The picture in post #4 shows armrests that curve downwards as they enter the seat back socket. The stepped rests had a flat section, then a step down to another flat section before entering the seat back socket, thus providing a high position away from the seat back and a low position nearer the mounting. It seemed to work quite well if adjacent passengers co-operated.

    (right) trialled on 1938 Tube Stock in the early 1960s, as fitted to 1967, 1972 I, 1972 II, with slight modification to 1973, D Stock, 1983 and BREL 1986 Stock prototype

    Thanks so much for that. I was beginning to think that I had imagined them. I may have seen them in the LT Magazine that my grandfather used to bring home as they would have been featured as a new innovation. Oh how I wish those dozens of magazines hadn't been lost over the years.
