Here are some more from a recent acquisition. The far left is a white spool. It has two symbols in green/blue on the top (one looks like a PS and the other looks like a TG). The next one over looks like it has a number (1610? embossed on the gray area on the bottom). The next one has no markings. The far right says PINCO-5 over 223 in an enclosed square on one skirt. Again, any help is appreciated.
