Probably circa 1920-30. Two copies; the original as posted on Facebook and a tidied-up version.

If you are talking about this one, it is a 20. http://www.imcdb.org/vehicle_539836-Austin-20-6-Landaulette-1930.html

I agree.

Maybe because it was possibly a gasoline powered car like this one?

Dimensions?

1929 Erskine???

The front fender appears to have no skirt - so no later than maybe 1932. The wheels look like 1935 Ford. But - the rear bumper looks to be a circa 1929-30 style two-bar type.

I wonder what the engine is. Proprietary? - Hercules, Wisconsin or??

I have a some very similar but no idea what they are for. I wonder if they are aftermarket replacements.

Maybe 1913 Buick at the front??

1914 Dodge - the first year for these. Could be 1915 as well I guess.

Deluxe CD introduced May 1931 according to The Standard Catalog. This one seems to be minus its 'winged radiator cap.' Or is it smaller than I think it might be?

The car on the left is a circa 1917 low price Overland. The white touring car is a Dodge - circa 1924. The touring behind it is a circa 1916 Buick four cylinder. The car with the chummy roadster styling, under the word 'Development', looks like a Stutz but I don't think it is big enough. At far right is probably another Dodge - circa 1926 - but it could also be an early Hupmobile Model A

Buicks use torque tube drive and Studebakers have open drive shafts. Maybe just your hubcaps are Buick? We have one Chev hubcap on our 1929 Plymouth until we find a correct replacement - thread is the same.

Dimensions?

Could be - more re the Jackson and the diamond badge here - http://www.mtfca.com/discus/messages/80257/99422.html?1248982791

Converted gas lights?

There is one of these in NZ with electronic fuel injection.

The radiator badge almost looks like a diamond, but the car is not a McLaughlin as far as I can see.

Looks odd on those fat tyres. The book says original size was 33 x 4, or 31 x 4 for the 1923 four cylinder car. I would have though original period replacement Disteel wheels would look more like these.

Possibly WW1 era or earlier?

Agreed. Not had anything to do with him but have heard negative comments.

Is the 501 all metric? The veteran 2B I had years ago had a lot of Whitworth in it.

What made me initially think Hudson Essex - clue the lights in the windshield base - was this photo that appeared on a local Facebook page a couple of days ago. Yes, there is a car in there - an Essex I think but it has features of both 1927 and 1928 - I think. One for the Essex experts.
