    I think the CS denoted an off road or street scrambler and the CSR was a cafe racer with swept back pipes and a very racy look.

    Hi Piero,
    If it's a complete model 33/CSR, that would make it an extremely rare and desirable bike. As Dave says, the CSR was a cafe racer. The rear subframe is different to the CS and roadsters. Many cycle parts (mudguards, stays, handlebar, exh. pipes, mufflers, seat?, footrests) are different too. There are pictures on the Internet, please peruse.
    As for the "G33/CS", there never was a model 33/CS to my knowledge. Maybe a previous owner took a G15/CS motor and restamped it. I don't think the factory would have made a bodge like this.

    The 33/CSR was probably a marketing ploy because there never was an N15/CSR, thus giving the buying public an alternative ..... Apart from the P11, all other hybrids were either G15 police/roadster/street scrambler or N15 police/street scrambler models. As for the G15 and N15 police and street scramblers, there is virtually no difference between them. It's probably a matter of selling the same product in different markets under different names. Common practice even today.

    Hi.
    Please, my 1967 N15 has the fork dampers with internal spring.
    My 33 fork comes me with external spring and not with the damper into.
    There is a mistake of the previous owner ?
    Thank you.

    According to the 1965 Spares List Supplement your forks should be like the 1964-66 G12 & G15 Roadster (i.e., 030037 Damper tube, NM18813 main spring) except gaiters (accordion), short cover tubes and clips replaced the long covers (clips are not listed, actually). Hope this helps.

    Hi Knut.
    I would say that the dampers dont have the springs.
    Must i add the internal springs or the external are enough?.
    Thank you.

    Hi Piero, do you want to restore your model 33CSR and/or make it a roadworthy bike? Then follow the spares list and rebuild your fork from the ground up using internal springs and the correct dampers etc. The cited spares book lists all the parts you need. Using the forks of an Atlas Scrambler on your CSR will make road handling at high speed worse. Good luck!

    Interested to hear about your difficulties, Andy. I have the Matchless variant, and have been working on a longterm process of a 33 replica, just because I think they're cool. Thanks!

    In think the engine was a low compression Atlas unit, whereas the cycle parts are slightly more difficult to obtain, if any are still around- The AJS Model 33 was the last AJS badged four-stroke produced. A Government subsidy allowed assembly to move to a factory at North Way, Andover, with an aircraft hangar on nearby Thruxton Airfield housing the Test Department.

    No, only 3 currently taxed. They are rare and this proves it.
    In comparison, there are 48 samples of G15 and 8 samples of N15 currently taxed.

    The majority of G15s are in fact G15Mk2.
    Of the latter, there are 6 N15 and 2 N15CS. They are probably N15CS, all of them.

    As far as I know, the AJS was only available as the 33 and the 33CSR. The 33 was the same spec as the Matchless G15mkII, and the CSR was sold as the G15CSR, 33CSR, and Atlas 750 SS ('66/'67). The CS was sold as the Matchless Scrambler and the Norton Scrambler. These hybrids, and the P11s, all came with the Atlas 750 with the dished pistons and a 7.5/1 C/R. According to the NOC, about 5000 of the G15/N15/33 hybrids were built between 1963-68 (and 3 one-offs over a year later for a dealer in Europe).

    Also, the 1958 Norton Nomad had the designation N15. 1959 was the P15, and 1960, R15. This was a 600cc desert sled in a Model 77 (non-featherbed) frame. I think around 300 Nomads were built in 1958-60, with a small number of 500cc variants also produced (maybe 40). Some of the N15 registrations may be this early model.

    All of the Nomads and N15CS/G15CS were export-only, but some have found their way back to England (forbidden fruit)
