Great photo. You can see the delight on both their faces. Early motoring must have been very exciting and cutting edge after many centuries of horses and cattle.

I wonder if that sidecar screen is plain glass. ?

I reckon laminated glass.
I had to get a windscreen cut from laminated glass for my Austin Seven.

From Wikipedia:
Laminated glass was invented in 1903 by the French chemist Édouard Bénédictus (1878-1930), inspired by a laboratory accident. A glass flask had become coated with the plastic cellulose nitrate and when dropped shattered but did not break into pieces. However, it was not until 1909 that Bénédictus filed a patent, after hearing about a car accident where two women were severely injured by glass debris. In 1911, he formed the Société du Verre Triplex, which fabricated a glass-plastic composite to reduce injuries in car accidents.

I would guess, almost certainly just plain glass. We had a 1930s Morris Minor many years back and a side window hit by a small stone (ahem) was just plain glass rather than the so-called safety glass.

Definately should have been laminated glass, (Triplex) by that time. With Triplex the glass can crack just like normal glass but it doesn't completely fall in as it's held in place by a layer of clear plastic.

I guess it's possible that someone had replaced a side window with standard glass in that car.

Never been keen on laminated glass. Sure, it tends to stay in one piece, but just look at those long, thin, pointy shards whereas toughened glass  is extremely strong but, when smashed, ends up as slightly rough marbles. One could quite happily sit on a heap of them. Now go look at a broken laminated glass and consider whether you'd sit on that. The relevance here, of course, is whether in an accident one ends up passing through the glass. Toughened is so much safer, yet RAC regulations etc demand laminated glass. Never figured why.

Are the front and rear wheels interchangeable ?

Hi Roy,

Are the front and rear wheels interchangeable

Not at that stage, the rear wheel has a brake rim on one side and belt pulley on the other
BSA offered two similar models at the same time, one belt and one chain drive , H and K but I cannot remember which is which
About 1927 when the introduced drum brakes interchangeable wheels were offered on the big V twins intended for sidecar use
