Hello fellow quartermaster fans (if there are any?),
I've been working on a number of Q's items from the footage so far. I think wardrobe hit it out the park on this. I haven't contacted any of the manufacturers in regards to validating these.
Couple of full body shots to get started
After some work I've managed to piece together a few of the travel outfit items so far :
Bag : 'Barbour x Land Rover Briefcase', 
Another (limited edition?) collab from Barbour used in Bond, Land Rover and Barbour have 'teamed up' on a few occasions. This is no longer in stock on the official Barbour site [update, these have been removed from the Barbour online catalogue] A couple made it to the likes of end clothing which were quickly shifted in the festive sales.
*Please be careful buying Barbour gear online, the amount of phishing and scam sites are unreal (granted some are more convincing than others!).
Boots : These are 'Clarks Nanu Rise Gtx'

As far as i can tell these are from the Clarks 2014 A/W, some available online and a couple have popped up on the bay [note; these are the 'Hike Rise GTX but there is a similar 'Hike GTX model').
Gloves : You can spot in some of the above image he's also wearing a marled grey fingerless glove, I believe these to be Barbour as well but can't be sure. These are a perennial if not permanent fixture to the Barbour range so I wouldn't rush out to buy them until there is more than my eyes and instinct as they could be any fingerless grey gloves at this point.
Parka : Jury is still out but my best guess so far is a Burberry 'Down Filled Fur Trim Parka' (useful name) again from the 2014 Autumn/Winter range, unfortunately no pictures. Don't know if I forgot to save them or if they were lost during a drive formatting, but they have (I believe} the same coat in Khaki (there is a new model in navy although it's pretty different, it's ribbed/puffy and is missing the strap on the hood), if you mix the two together you'll see what I mean,I'd love to be proved wrong though!
Hat: No idea about the Beanie 
Jumper : I must say I've been searching for months and have no sniff of a trail, I'm hoping it's not another custom made like the DVN Cardigan. If anybody even has a guess I'd love to hear it (the closest I could find were by Boss and G-star and that can't be right...)
From the released stills:

Office wear: No idea! Here's some clear shot's from the comic relief skit (he's wearing the same in the new trailer). Personally love the shirt if anybody has any ideas?

Thoughts? 
amazing research, I hope you manage to get all
. The one facing us with mad data looks like one of these weird transforming tablets (silver hinges, odd screen edge). Closely resembles some Lenovo offerings.
