Looks like a 1955 model year. Fitted with a better B33 8 inch front brake. A 1960 would have an alternator and coil ignition, so no mag or dynamo.

Grandma's eggs and all that but someone's whanged in a UNF screw on the front mudguard stay fork mounting, and the front brake needs attention too. ;)

Hi
Not worried about odd nuts and bolts or all the terrible silver painting but what attention does the brake need?  not got that far yet :)

The arm is going past 90 degrees where it starts to become ineffective. Lining may be worn You can try turning the arm round to set it at a different angle.
