Hi,
As confirmed above, it was built by Westfield, around 1940.
If you can give us the two sets of numbers off the bottom under the crank, than we can date it to the month for you.
There will be a long number, starting with a letter (possibly E or F, you'll need to check carefully if it's one of those, sometimes the bottom bar of the is lightly struck on the curved surface), followed by five or six numbers. Above that will be a single letter, followed by one or two numbers from 1 to 12.
Best Regards,
Adrian
