You English is very good, don't worry. (And far, far better than my Russian!!)
We can all understand you perfectly
I just realised the bikes you posted last night are Swifts because of the characteristic arrow.
I was slow there!

I have already sent the links to the Coventry Transport Museum.
I'm sure they will be interested to see them.
Got an email from them this morning, but no progress on my Swift ID yet.
I know it is definitely one of the last made.

I may spend the Christmas holiday in Coventry and will take my Swift if I do. (By train)
And then I'll be able to visit the museum and look at their archives.
