While I am aware that they make them for non-aircon Mk2's as well, I was confused by the catalogue numbers. As I said, my coaches both start with 305, but the kit that includes 305 numbers is listed as "Mk2E/F." But as muddy has explained, the windows I'm looking for are apparently included in the "301/302/303/308" set.
I don't mind doing a bit of filing. Actually quite used to it, having built a small fleet of H0-scale coach kits.
The door glazing? As far as I can recall, without having the coach in front of me, that was as sunk in as the rest of the windows. Might have to reassemble one of them to check.
So that pack is for all non-aircon Mk2's, even though my ones start with 305?
Filing out the smaller windows might be a bit more challenging than what I've done so far, but if it will improve the looks of the models, I'll give it a go.
As I don't live in the UK, I'd prefer to contact them via e-mail, but as long as I have the catalogue number I can at least look them up.
Thanks for the help!
