Ian, I suspect you and Bruce are talking about different subjects. I recently acquired a couple of Chinese trimmers, which I found are sold under a variety of brand names, including Victa, Pope, Parklander, GMC, Sanli, Aldi/Gardenline and various others. There seem to be as many more such oddball brands it is sold under in the UK and the US. It seems to me that the key point here is that apart from Victa (which doesn't manufacture much these days) none of the brands involved manufactures anything, and if their products are in any way exclusive, it is only by choosing which of the actual manufacturer's standard production options they will specify. By the way, it turns out to be quite a good trimmer, probably the easiest to use I have ever encountered.

I've seen the GMC brand on air compressors, mowers, power tools, and other things I can't recall off hand. The point is, GMC is a brand attached to imported generic goods, as are all of the others I have mentioned. It is a bit like collecting Victa 2 strokes marked with various store-brands. No reason someone couldn't do it, but I don't really see why most people would want to.
