This used Flower Center Basket Weave stamp was made by RBS (Roth, Barnes, Stohlman). It is tool number 507 and is a genuine RBS stamp. The tool measures 17/32" in length and 9/32" in width. This stamp is lacking in detail (see photos). These old tools do not come available very often, so don't miss your chance to add a great stamp to your collection. It is ready to perform and still has many miles left in it.
