Hi,
In Avis/A-model 1/72 kit of Hwaker Hart family there are two versions of bottom slide hatch - with and without window. In all photos I found in net it is always without window from bottom. In which variants it was with window? Namely - I want to build two radial Audax mutations - Avro 674 and Iranian Audax (Nisr). I think that Audax as designed for observation can be expeted to have window in hatch. And I think the camera 's circle opening from bottom is always for all Audax (it is not present in Hart - as far as I've noticed) But perhap someone cn help me knowing it for sure. And what about Hartbeest? Hart trainer has not those hatches at all, isn't it? I will appreciate any help - I have Mushroom's book "Hawker Hart Family" but did not found this there.
Regards
Jerzy-Wojtek
