Mystery device on TBD Devastator

[Mark Allen M]

I have always wondered how that tilted-back open pilot's canopy thing works? It really tends to make scale models look amateurishly fitted, and is a curious feature in any case.

Here's a few additional shots.

Thanks Mark, wonderful photos as always, they really make obvious why it's designed as it is.

The old TBD is one of the types that just grabs me, that I find fascinating for whatever reason.
