This is a set that has the B-58 on one side and then the Spirit of St Louis on the other side. It’s one of the best looking sets that I could find. It is old. Probably mid 1960’s. It is marked sterling on both cuff links and the B-58 has Pat Pend on the toggle clasp of the post. The post also swivels. Please visit my store for other great items. I will combine shipping on multiple purchases, but please ask for an invoice before you start paying for individual items. Thank you.
