What are these? They connect to a pipe or something. Idiotically, I can't remember the machine - big Diamond T or White maybe, but think I've seen them on other lorries. Red on the right. Yellow on the left. Sorry the red one is fuzzy, but you can see it at least. Cheers, and apologies for shambolic nature of the query This may be a question inspired in drink - I shall have a shufti at a few more pics and determine if they're common or just on one type.
http://data.primeportal.net/transports/jon_arnold/diamond_t_model_t981/ This ia a Diamond T T981 with front fender, winch rollers, and soft top. The owner tells me there are two post war mods - The Yellow and red air-brake connectors on the front.
Strewth. When you're good... Ta! Suddenly it makes enormous sense - improving the braking on a 70 year old high tonnage truck.

Our fire department's first tanker truck was an army surplus and had the air brakes piped out to rear, for trailers that had that feature. The connections were painted olive drab, like the rest of the truck, when we got it. On an aside, we hated that vehicle. It drove like a block-wheel wagon and needed a football field (or cricket pitch) to turn around, which was an issue when supplying water in some of the tight places people put their houses. It was an old truck and the brakes were spotty at best. After they failed the second time, we refused to drive and the board of directors funded a commercial truck for us to use.
Palm couplings for air lines to connect to a trailer. Needed on the front as it is a lot easier to manoeuvre a trailer in confined spaces by pushing instead of reversing. http://img.photobucket.com/albums/v293/wheelnut/P1000650.jpg
It's for the optional frozen yogurt / espresso / margarita makers that are available. Much like the Tea stoves in Brit Armor.
