I agree with you about "dressing up" aircraft. In this case, keeping the original greenhouse canopy and the naked gear legs would have made it unique. I suppose I'm a pedant too - having flown both the T10 and an RCAF DHC-1B, I appreciate the lines of both and I dislike seeing Shuttleworth's T10 in RCAF colours.
At least CVM looks, at first glance, similar to a 1B. I thought it was ex-RCAF until I saw the throttle quadrant and then I was confused.
The link I posted earlier states that the new canopy came from the US, so presumably it is for a 1B. If you meet the current owner in Omaka, perhaps you can ask him about the windscreen (or measure it)?
