    The MA-1 "Technical Mainual - Overhaul" (T.O. 5N10-4-2-3) manual says "silicone fluid DC-200 having a viscosity of five centistokes". Such fluid should  be available on the market (search the internet). The manual does not give further specifications. I for my part would thing any (clear) silicone fluid with that viscosity would do the job.

    Regards,

    Hello Robert,

    Do you have the specific description and the viscosity of the DowCorning silicone fluid?
    In the past I have seen that  this kind of fluid is still on the market, but to be able to buy
    the correct one I need the specification.

    Thanks in advance,
    HermanD
