IWC 6.4mm Yellow Gold 1940s-50s Watch Crown, Tap 1.2

Vintage new old stock IWC watch crown, yellow gold in colour and wrapped around a brass base metal core. These crowns featured on the 1940s-50s IWC models and would have fitted onto the larger size mens models. I have included photographs of measurements but the crown is 6.4mm in diameter and the tube is 1.6mm wide. Tap size of 1.2. This is a hard to find size and I doubt I will ever get any more of these in stock and available for sale once they are gone.
