Theft Description

It was stolen on the 2nd of January from Westfield Park, Redland Bristol BS6 Theft captured on CCTV, bike was removed from my van which was off street but sadly unlocked. Its a family heirloom passed down to me by my uncle who passed away a decade ago. Any information greatly appreciated, or tips on how to find this bike. Reward not reflective of market value but great personal value. Thanks, Rubin
