Hi
The Vickers was made in Sheffield but I can't tell you anything about the others other than they were made towards the latter end of the hickory era when they started to number the irons as well as using the old names mashie, niblick etc so these are from 1930 ish, do they still have the old leather grips ?
By the 30s millions of hickory clubs had been made so there are very few really valuable ones about these were cobbled up by blacksmiths before 1900. If you,re wanting to sell I can have a look or you could send me some pics.
Cheers Tim
