Just got these today.
Full brogue in Teck shell cordovan with red lining on a chanelled leather sole. Quite sleek for Trickers . Also waiting for a Burford boot in dark brown and they'll join up with Wetherby boots and Keswick shoes.
The other shoe in the last pic is a Church's Grafton to give an idea of relative shapes and in particular the trimness of the welt on the Trickers shoes. The sole has quite a nice bevel too, which you can't really see in the photos.
Sorry the pics aren't great, there's no natural light at the moment.
I asked Richard at Shoehealer about these. He thinks they are likely based on a model called the Tetbury that came in black scotch grain, on the 4537 last.
I have two Tricker's on that last. Belgrave first (Herring shoes photo); Mayfair second (my photo). I think this last fits great; I'm a big fan. And BTW, I just purchased a C&J on the 337 last, and the shapes are almost identical.
