Good morning
On my website
www.richardwheatleymuseum.org under compartment box2 there is a photograph of a rare E. Kerry dry fly box. This box seems to have only been made for Kerry's.
I also have a 1933 catalogue which shows the items that they sold that year. Of great interest to me as they purchased a number of items from Richard Wheatley (including the above). If you p.m. your address I will try to photocopy it for your research although catalogues of this age do not always copy well. (94 pages and the cover)
Anything that you discover about their dealings with Wheatleys and their stocking of Wheatley made angling equipment would be considered a fair trade
Best wishes and good luck
