Small RF Prototype Enclosure Gold/Aluminum 4x SMA Connectors "ST PRA V21 1949"

Small RF Enclosure. Possibly a prototype semiconductor assembly. It was received in a lot of optical and LIDAR items. I'm not sure what parts might be gold or gold plated. One of the SMA connectors has a bent center pin inside (see photo). 

Weight of item is ~2.25 oz.
