the smashed up one doesn't look like the rest....its shiny so it must be a stamped Form 400 verses the Dull Cast ones,but cool to see those canadian ones in service!
I found the shiney Form 400 here It's the second one in the pic. It appears the Form 400 was tilted towards thic pic and that's why it looked shiney (we see the reflector in this pic). Sadly, those first two Form 400s don't look like they're maintained.
