Mauro from Veneto has researched everything about this photo

Mark in New Zealand was astonishing in his research on this photo;
The car sharing the forecourt with a biplane is a 1926 Armstrong Siddeley Broadway Saloon. Further research also established that biplane is likely a radial engined cca 1937 Blackburn Baffin Torpedo Bomber, built in Brough, Yorkshire. 29 were acquired by RNZAF and few were converted to training aircraft

Avro 616B Avian IVM ZK-ADQ (c/n R3/CN/435) with Genet Major engine refuelling on what looks suspiciously like the main street through Saltwater Creek at Timaru.

ZK-ADQ was constructed as G-AATV for Shell Mex Company of Egypt.

It gained its UK C of A on 30-01-1930 and was cancelled in March of 1933 to take up the Egyptian marks SU-AAG. It took up its old G-AATV registration again from 12-09-1934 with Flying Officer Geoffrey Twyford Jarman of 47 Squadron RAF, Khartoum, Sudan.

Its UK registration was cancelled on 02-03-1935 and it then became ZK-ADQ on 05-05-1935 with K R Johnstone of Timaru.

Other owners that I know about were P W Wilton; Charlie Liddell of Wellington from 10-05-1942 and then Southern Cross Aviation Services Ltd from 19-05-1948.

It crashed at Willowbridge (near Waimate) on 13-06-1948 with ownership going to J H Craig on 05-07-1948 and was cancelled on 29-10-1948.

At some point it was fitted with a Cirrus Ermes II engine. I found a picture of the same plane dtd 1948.

considering the notes of NZCarned about Europa, the Todd Family business, the car period, I would date this image at 95% probability back in the middle of a Summer day of 1933 or 1934 (100% sure between 1933-1939). Summer because looking at the inclination of the sunrays.

Europa Logo was established between 1931 to 1939 but regulation for the mkt changed in 1933 most probably modifying the layout to get updated, Plume logo was modified for sure in 1939 introducing the red horse on logo. However on Exxonmobile website is stated that in 1934 was introduced a new brand (by Vacuum) named "Ethyl", Australia's first Super grade motor spirit. Then there is no trace of Ethyl writings in none of the Vacuum pumps, just Plume or plume gasoline on the first 3 pumps from left.

ABOUT EUROPA LOGO The Todd family also founded Europa an oil importing and retail business that owned terminal services at four major ports and a chain of petrol stations across New Zealand. According to the Todd Energy website, this business was founded during disruptions in the petrol industry in 1929. Europa was originally named 'Associated Motorists Petrol Company Limited' (AMPC) and was formed in 1931. The company imported petrol from the Soviet Union from 1933, and was supported by the New Zealand Farmers' Union and various regional Automobile Associations. Because of price under-cutting by overseas oil companies, the government introduced price regulation of petrol from 1933.

ABOUT PLUME LOGO The Vacuum Oil Company began operating in Australia in 1895, introducing its Plume brand of petrol in 1916. The Flying Red Horse (Pegasus) logo was introduced in 1939, and in 1954 the Plume brand was replaced by Mobilgas.

Then we are in Timaru NZ in the middle of a summer day back in 1933 or 1934 (95% sure). We have a Armstrong Siddeley Broadway Saloon which I agree 100% and a 1930 Robinson Redwing MK II for which I still have not found certainty, just 90%. Someone has some ideas? have you found this image with higehr kB? the one I am studyin on has just 181,8kB and doesn't let a good read of the pump writings.

I think it should be a Robinson Redwing MkII with engine Genet II. This kind of airplane was made for private purposes and sold on kit. In particular some planes were delivered to NZ after 1932 from the ''London Busman Flyingclub'' in Broxbourne UK. They built just 12 units and they suffered weakeness to the landing gear. The engine is a radial 5 cylinders as the Genet II is; you can find it on google. I am just not sure about the plane because the landing gear on the picture goes through the lower wing while all images found for the Redwing have the support in front of the wing. Another peculiarity is the vertical tail which has not the same shape. One of the idea I had is that the plane could have had an accident, they broke both the tail and the landing gear, therefore they reinforced it taking advantage of the fact that this plane has the possibility to be stored and the wing can bend 90° toward the tail.
