Cruisin' on my Bluebird
Here’s the bottom bracket number View attachment 1065031
This is a Westfield built Elgin.
F is the letter, 1941 is the year.
There should be another date code above it, which will give you the month and year the frame was made, it will be located almost at the junction of the bottom tube to the hanger bracket..
@Mercian may know more about the bike.
