    Hello Crapscatter,
    A look through the Mirrlees company history on this site suggests some possibilities. Have a look at the un-named series of 60 bhp per cyl built from 1934, nd the subsequent TL series with 4 valve heads and upgrades this would have produced more than the 60 bhp per pot, so probably puts it in the frame for 4 cyls to deliver the 125 kw at a 50 Hz alternator speed of 750 rpm. That's my speculation at this distance, someone else may be able to find something more definitive, Regards, Mudmover. :?:

    Think you'll find itmight be a UA4 very similar to the UA5 at I F . Generaly sound like a handful of nuts in a heavy tin when running!
