Runflat

Not sure I understand the context of the question/relevance to Alvis.  Anyway, home grown WWI subsidy trucks used steel wheels - I'd need to double check if that was actually part of the specification - whereas most imported trucks did not or were inconsistent.

I think you mean to link to this one https://www.iwm.org.uk/collections/item/object/205189024

Ah yes!  I was imagining something on a very different scale.

An intriguing early trailer for sale.  Probably not military but interesting nevertheless.  Why don't they show a picture of the name/data plate!?

Here's one for sale should they take your fancy: http://www.elalamein.eu/f60l-ambulance

It's either a F60L or a C60L - 'F' and 'C' for Ford and Chevrolet respectively, '60' for 60cwt (3 ton) and 'L' for long chassis.

The C15A was a Chevrolet 15 cwt, with 'A' for four wheel drive (as opposed to C15 for the two wheel drive version).

Of course it would help if I could type!  I should have said Alvis-Straussler Ltd.

Some info here: https://someinterestingfacts.net/straussler-armored-car-ac1-ac2-and-ac3/

Can't see it!  The number doesn't help - it is part of a series allocated to the Middle East. 

Well, the first armoured cars by Alvis-Staussler Ltd were built in 1937.

The have been various militarised Minxes on the scene over the years - some here: https://www.flickr.com/photos/richard64pics/albums/72157691647093532

Hi Tony, welcome along.

I see the Kegresse website lists you having two vehicles? (Ref. GB5 & GB6)

Interesting, with the 'H' serial number and the front brackets for the winching spades, presumably another converted artillery tractor?

(There's one on Milweb at the moment:https://milweb.net/webvert/a3886/95991 )

Looking more carefully at these photographs - the position of the star on the side would suggest there were at least two of these loudspeaker vans.

There are several pictures of these K2/Y loudspeaker vans (possibly all the same vehicle!).  Other vehicles were used, such as White scout cars.

Pictures below from IWM official collection.

Neither, it's a WOT3.

Here's a better picture of the Minx for you.

It's clearer expanding the online images, rather than these low res images - it's Royal Navy Voluntary Transport.

The car in the last three is a Vauxhall, of course.

Some IWM pictures.  The caption for the first two say they are drivers from the Women's Naval Car Service - but I can't read the shoulder flash!
