Trying to identify my Armstrong bicycle Can anyone tell me what model Armstrong this bicycle is and possibly what year thank you
It looks a lot like this Armstrong

The seat stay bolted to the seat tube may be one difference.
Based on the conversation in the thread...

this model is a 1953 so the rear hub tells me

If your bike does have a Sturmey Archer three speed hub you may be able to date the bike by the markings on the hub.

The article goes on to explain how to date older SA hubs.
Here is the 1950 Armstrong catalog.
This picture looked to me like a good match

Three speeds and dynamo hubs were offered as an option
