Hi David,thanks for that. Brandbright are sadly winding down their business as the proprietors are going to retire and the only 32mm wheels they have left are 16mm diameter ones, which are far too small. As for the other method you mention, I now have a couple of LGB coaches and have checked them out regarding adjusting the wheel spacing. The wheels are indeed the old "Triang" type you mention but before cutting any material off the stub axles I tested a couple of the wheels for running qualities on my Peco SM32 track and found that the very deep flanges fouled the chairs on the rails, so back to the drawing board!. I measured the depth of the flanges using my digital micrometer-an extremely useful tool, if you haven't got one I would thoroughly recommend getting one-and they came out at 3.5mm, whereas the 16mm Assocation standard is for a flange depth of 2mm, hence the chair-fouling. Anyway, I measured the exle diameter and it came out at 3mm, and luckily Binnie Engineering do some wheels that are are a push fit on 3mm axles so I have ordered some. The LGB wheels are approx 31mm diameter whereas the largest Binnie ones are 29mm, but I can work with that so, fingers crossed, everything should work out OK.
