I have a few of these ringed inlaid monogram chips for other letters in the same style. Wide Ring is Seymour's Code PO-CA to PO-CZ. Narrow Ring is Seymour's Code PO-GA to PO-GZ. I've been collecting inlaid monograms for a while and I believe this style is rare. I'll trade, straight up, for letters I need.

Wide Ring: A (blue, black, red), B (red, blue)

Narrow Ring: F (dirty white, pink)
