Here's a pair of colorful porcelain cable tops made in the USA. (L to R):

1. Cool Mustard U-460 (closest I could find) incused marking Locke 8881 USA V. Looks Mint. May have some teeny use marks or scratches. $12.

2. Beautiful Butterscotch U-499A. Unmarked. I believe this is a Pittsburg product. 1 match head glaze flake and 1 match head rough spot. $21.

First email that says they will buy them gets them. Buy both for slashed price of only $30. $8.40 postage for first one. Actual shipping for more than one. Will combine with other sales offerings. Thanks!
