I haven't been very active with insulators for a year or two. Out of curiosity I was checking through some old bookmarks and found this current auction for somewhere in South America. I'm not up on foreign porcelain but at first glance they all seemed pretyy much the same to me - white porcelain with tie wires. Then I looked a bit harder and found maybe ten different types. Some have good markings and I suppose others are unmarked, so that would increase the number. I imagine the postage would be significant, but you would have a number for sales stock. I always seem to find things I'm not interested in.
