Hi Pacemaker, certainly the straw plait trade continued down the road in Marsworth, Ivinghoe and elsewhere as my Mother remembered her mother hiring a pony and trap to take the rolls of plait to Dunstable i n the early 1910's to the dealers for the hat trade there
If you go to Genuki ,click Hertfordshire ,and enter Chris Reynolds site ,he has items on the strawplait trade in that area, where Herts, Beds and Bucks boundaries all meet up He may be able to point you in the right direction
best wishes Marton
