So, the BR Original Specs would work, I think. The others are wider.
The Westpoint fabric which they are also made of is quite interesting. It's a bit shiny, very smooth. And probably due to that the beige colour, which I have, changes according to the light. The Pherrows are also very nice, with the khaki being more of a yellow-green. They fit smaller, I have a 36 vs. my "normal"34. The Deluxeware have currently a bit more of a brownish khaki colour. They are made of LHT chino cloth, but tightly woven. The TwoMoon are also great, but fit smaller like the Pherrows.
The khaki is also more of a green-yellow.
The 529 is a slimmer fit. The 536 are a bit wider. Colimbo Overland campaign trousers might also be an option. They are still available at mushman in 36.

The Freewheeler ones look very good, too.
