The photo you posted of the brass ashtray from the 63 Club reminded me that I have a brass ashtray also. Mine was presented during my departure ceremony/party and is engraved with signatures of some of the personnel assigned there at the time. Some of the legible names are VAdm Snyder, BGen Williams, Col Peters, Lt Col Blanton, Major Delano, CPO M Johnson and others.
We were also presented with a USTDC necklace. It's the USTDC metal logo badge mounted on a piece of green jade. I am also enclosing a photo of the necklace.
