They were made by Tricker's, now they are actually made by Sanders. (from circa 2 years)
You can easily spot the maker seeing how the sizing is writed:
Tricker's , writed like all trickers in the side lining
Sanders, writed in a white label under the tongue
I never tried the Trickers TB, but I owned various Sanders TB,
I wear Uk 8,5 US 9,5 as my other Sanders Shoes, I found their last shorter than other makers.
I wear Uk 8 in most english Brands, sometimes 8,5
