Heli1: You are absolutely right of course, Bill Armstrong it was. Its been so long since I heard that name!
Sillohed: I know you are most likely searching for information on Autair's Canadian ops but the available information seems to be somewhat scarce. I have another S-55 photo and that's about it!
In the meantime and from their UK operations ..

'ZX' was imported to the UK in 1966 and (as with Brian Bicker's G-APDV above) was sold to Shackleton Aviation (does anyone know who they were) in 1972. The same year she moves on to F & DM Hewitt Ltd. and the following year is bought by Tywford Moors. ZX ended up being bought by Bristows in 1974.
