Cool. The first looks kinda like a small, mid-'teens motorcycle club. The second looks like an early ride-in bike show.
That guy in the first pic, I've got gloves like that. Those long-cuffed gauntlets. They're actually pretty good for brisk weather and keep cold, damp air from rushing up your sleeves and freezing your arms. That, and they look WICKED.
The front one of the three bikes is a spring frame, which I think makes it a Powerplus.
I also have a pair of old gauntlets, a memento of a friend who died a god few years ago now. 2 door is right, they really do keep the breeze out of your armpits.
There is every chance there are some aussies there. The British were the majority in that area, but there were some Australian troops there. And we know how much the aussies like the Douglas machines, they are still riding them today.
The British had 15 divisions there before it was over. The Australians brought a lot of horses with them, along with the "New Zealand and Australian Mobile Veterinary Section AVC" They were still a horse mounted army in 1915
Tough bunch of messengers there, whatever country they were born in.
Mr. B, was interested in your comment "Diggers?" Iv'e only heard that term used for a lowly tribe of early California Indians (not the bike). Is that also used for some Aussies?
Jeez Luweez! Wouldja look at the cylinders on this thing. The bore's as big as his ankle and the stroke is as long as his tibia! That's gonna have a bit of torque there.
