Re: Scored an english armstrong
Essentially your Armstrong bicycle is the same as a Ladies Raleigh bicycle of the same year. In fact your bicycle is almost the same as my 1947 Ladies Raleigh all except for the Dunlop alloy rims, rod brakes, prewar design coaster hub and the Terry three spring saddle.
As a rule of thumb when it comes to straightening your forks the fork legs should have no backward curve or kink. They should run completely straight until they taper into the forward curve at the lower end.
By the way I think you are right about how your bicycle ended up where it did. The possibility that it came adrift from a vehicle and bounced hard on its front wheel before ending up in the weeds at the side of the road would be highly likely in my opinion.
