3/8 UNF thread fittings for the brake ends are still available but not as common in Europe as metric fittings. Ebay an the Internet are good source of such things but companies such as RGM list ready made stainless brake hose on the website also.

My later Lockheed calipers are 3/8" x 24 tpi (i.e. UNF), so it's more than likely they all were. The M10 x 1 metric threads used on the hydraulic hose connections such as the Goodrich type will fit into the caliper but you can tell that something is wrong as the fitting flops around in there too loosely.
As with all these things, it's out with the vernier, thread gauge and increasingly these days, the magnifying glass if you want to be certain.
