Vintage 70s Chunky Solid Silver Texo Keyring

Super cool and very rare (no other like it on the internet!) solid silver keyring. Vintage and by the styling from the 70s and signed 'TEXO'. Short length of chunky curb chain that permanently clips to the ring (squeeze and open) and, on the other end, to the fob, which has a retro decoration on one side and TEXO on the other. Just over 11cm long and 28g in weight. This would make a very unusual and stylish gift for a man.
