Something that has just come to me is that the Salamander airfield crash tender was faster in top gear, 10.05 ratio, against 12.9 in a Mk1 Stolly, and this was running at approx the same overall weight, and they both have the same 1st gear ratios.

I have spent much time standing on my head working inside them

Hi Richard.
Due to Australias distances I am looking for gear ratio options on the stalwart.
A 80 kph/50 mph maximum speed with a 60kph/40 mph cruising speed at say 2700 rpm would be fantastic without changing the first gear crawler ratio for off road work.
I know the Saracens used by the Australian army topped out at 72 kph with the preselector gearbox and different bevelbox ratios.(tyre size too)
I have no idea if the Salamander used a manual or preselector gearbox and ratios.
Only three salamanders made it to australia and they most likely dont exist now.
I was thinking if fittting Sarasen components could give a wider spread of ratios on a Stalwart gearbox.
Do you have any idea of what Salamander/Sarasen bevel box/hub reduction/ preselector box ratios are .

Ron
