Went to look at a group of 900 insulators advertised on Craigslist. He was willing to sell them for about 50 cents a piece, but they were mostly more of all the RR insulators I already have too many of. He did have a couple of boxes that he didn't want to sell, but I talked him into it, and probably still paid too much.
Here are 6 light green LRIs, all with some point damage but good bases. I also got a bunch of white porcelain ones, one marked Kretzer on the top, one marked RH Co on the bottom, most marked PP Inc. on the bottom, and a few of the wide groove ones.
