But I guess we will be sometime in the late 1930s or ‘40s.
The photograph perfectly captures that moment just after the end of the shift at AEI.
The long line of trams waits for the workforce which is just appearing through the factory gates.
All of which is well documented, so instead I concentrate on the detail. The first of the workforce is out of the factory and hurrying to catch the first tram. It is a scene captured countless times in photographs and news reels from the period.
What is missing are the hundreds of of people who any minute will appear on their bikes, reminding us that this was still the time when the cycle was a cheap alternative to the tram or bus. And of course what we won't see in any great numbers are workers driving home in cars.
I had hoped that the products in the shop might give a clue to a date. But Robin cigarettes were being marketed at the beginning of the last century and were still being produced in the 1950s, long after our line of trams had gone to scrap heap.
A timely reminder that this was still a time when smoking was common place and when the upstairs of the bus or tram would be blue from the tobacco smoke.
Much of which would be from the roll up which like the tram is almost a thing of the past.
