Mobil DD extra heavy oil

[Dinwoodie Cutlery Concepts]

Does anyone know of an equivalent or something close to this oil? My Burgmaster calls for it in the gearbox I tried some lighter spindle oil and it ended up all over the bench due to the lighter viscosity.

Looks to be an oil in the 40 weight range {140 cSt at 40ºC and 14.4cSt at 100ºC}

The data sheet at Mobil has a DTE oil of this name and on the same data sheet it has an oil with a BB name. I suspect DTE to be a more modern version of DD.

Google finds nothing on DD
