This call has been assigned to me since December 2007 - my first VR2 call (I was G1HVQ then G0FYG before I came to Hong Kong) being VR2LH, issued to me in mid 1994. Although licensed I never actually transmitted from VR2 until December 2005. Amateur call signs previously used in Hong Kong started with VS6. The assignment of the VS6 series call signs was discontinued in August 1993. The VR2 series were then introduced (existing holders of the VS6 series call signs were allowed to retain these call signs in parallel with their newly assigned VR2 series call signs until 30 June 1997- Britain handed Hong Kong over to China on 1st July 1997). Incidentally just two letters after a VR2 prefix signifies that the holder has passed the 12 wpm morse exam and originally meant that the amateur held a 'Class A'(full) license thus allowing HF privileges. All VR2 amateurs now have access to HF, whether they have passed a morse test or not, so apart from vanity two letters after the VR2 prefix means nothing in reality. VR2CB was issued previously to another amateur however I have no information as to who or when other than there may have been a station with the call 'VR2CB' active from Fiji in the 1950's - if you know more on the previous VR2CB license/station please let me know! I'm QRV on HF, mainly 10m SSB (here in Asia most 10m SSB activity takes place around 28.490 during these low sunspot times) or more recently PSK31 on 30m or 20m, using a 10m monoband vertical ant or the odd short bit of wire (when I get the time and energy I will try to get the mag loop up and running again). If you really do need a QSL card send it direct as the buro takes a while and although the guys do a great job it could get lost my end/damaged in a typhoon/eaten by bugs or rot in the 95%+ summer humidity! By the way if you send  a QSL card via the post/mail I suggest that you do not write 'China' or 'Peoples Republic of China' on the envelope as it will probably get sent elsewhere rather than straight to Hong Kong. And sorry to say for those chasing IOTA my QTH is not on HK island!
