They're Alko, yes sir. They look like type 2051. If you have a look around the outer edge of the brake back plate there'll be a 4 digit number stamped in to it (my suspicion is 2051), something like 2051, 2361 etc. This gives you the brake type. i.e. 2051 = 200mm drum diameter and 51mm width shoe. 2361 = 230mm drum and 61mm wide shoe etc. You get the idea, I'm sure!
Your cables should be stainless steel (if they have a red outer sheath this denotes stainless, black means mild steel) - they should be stainless as standard from Indespension, but whilst it's stripped it'd be worth lubricating these at the same time, just to make sure they're still moving ok.
You should be paying around £50.00 ish for an axle set, for a single axle trailer (two pairs of shoes and the retaining springs).
