Just bought this one from Ebay, as a buy it now for a very good price. Seller had it listed as Australian, as the maker is the West Aukland clothing company, though they are a British company. Label says 46 pattern and 1948 dated, though it has had the open collar officers conversion done, which is a shame, but hey, I can't complain. It has leather football buttons and green backed captains rank pips and a pair of WWII date 7th Armoured division patches, which is nice.
These are the sellers pics and as always I will post better ones when it arrives.
