What is that big beautiful brass era roadster in Richter's orchard?

This looks to be a 1912 McLaughlin Model 29 roadster. The coach lines around the door are a little different from the rest. If you spot some differences from the same year Buick that is to be expected. Right from their carriage building days McLaughlin craftsmen were known for top quality builds and the best of paint jobs. These cars were not sold in the USA, only British Commonwealth countries.

As usual the vagueness of the photo makes it difficult to draw definite conclusions, but a number of details like the seemingly flat-topped radiator and the inlet and exhaust pattern of the engine point at Buick (1913 model 31). Other details fit in like the roadster fender pattern with vizor at the front. However the Victoria body style with the small diameter round fuel tank and double outlined side door is definitely not a Buick standard body. As the photo probably was made in Canada, it could be a Canadian variety?

It appears that they are either changing a tyre or repairing a puncture. The vehicle in the background has the left front rim removed, most US vehicles in the early 20th century had separate removable wheel rims. My own 1917 GMC Model 16 WW1 Ambulances have them. You often see just a rim and tyre carried as a spare, these rims were bolted through fitting ears or flanges to the main central wheel. My guess is that they have jacked up the vehicle in the background, and one of them has sat on the box in front of the wheel whilst he un-bolts the rim from the wheel. So why are they so far away from the vehicle whilst they are repairing the tyre/puncture? I would guess, judging by the rural location, that they are possibly near an animal water trough, why? Well when you have a puncture the easiest way to locate it is to put air in they tube and dip it in water and watch for the bubbles. Once located you can fix it, refit the rim, and be on your way.
As to the make of car, that's beyond my knowledge, but I'm sure there is someone out there with in depth knowledgeable late 10's/early 20's US cars who could enlighten us all. Possibly Dodge, it's not Ford Model T body I recognise. Colour scheme? A dark colour, probably dark blue or black, over a much lighter one, could be anything from cream to yellow or even light blue, it's anybody's guess.

Looks a bit like an early Chevrolet (a "Little" possibly), and look at the front wheel - no tyre! So lad, they are changing a puncture... common occurrence in those early days of motoring! Of course, two are supervising whilst one does the labour!
