Freddie Grubb - a little history.
Freddie Grubb, set up shop in Brixton circa 1914, financed in part by Charlie Davey (I have a friend who is a member of the Davey family).
1919 Freddie Grubb set up in a shop in Croydon with"Ching"Allin (Allin & Grubb).
Earliest known genuine Grubb frame is about 1922.
Holdsworthy took over the Grubb name in 1952, these Grubbs were not highly regarded (even by Holdsworth) they were their second grade bikes and were built in 531 plain guage and rarely, if ever, full tubesets - the name however remained attractive.
The last true Freddie Grubb shop appears to have been in Wimbledon.
I take an active interest in frame builders/shops in this part of the world; what is now known as south London.
