I'll just put me Anorak on again...
My "records" show VR-BDN & VR-BDO as being in transit from USA to Malaysia in
Jan 1970 where they remained, working for Esso / Elf until August 1972.
In October 72 they were transferred to Singapore
61470 (VR-BDN) became 9M-ARV
61471 remained as VR-BDO and they worked for Conoco
They then appear in Natuna Besar and on to Kuantan with Conoco up till May 73.
9M-ARV went back to Esso Malaysia in June 73 and came to the UK in May 75 where it seems to have operated as 9M-ARV out of Aberdeen for some time.
It became G-BDRH in Feb 76.
VR-BDO became UK based G-BBGS in August 73
These were the first two S61 with Bristow, my earlier info refers to S61 debut in the
UK for Bristow.
Hope this is of interest (or have you fallen asleep already!!)
Can I take me Anorak off again now, its a bit warm, even for Shetland !!!!
