I took a look on my two Bangers (blue and amber windows) and am I right in the assumption, that they also have no mounting pegs?
does it also apply to the Pipers?
I can see a ridge in your model with orange windows (as expected in this later issue). I also think I can see a tip of a ridge in your blue window model but I am not certain. These are paired ridges/bumps and are located on the inside of the body casting just behind the rear window edge.

I checked my Bangers once again and you are right - both have mounting pegs.
My Piper with amber windows has none, my Piper with blue windows does have such a casting.
Now everything is clear so far and I am ready now to have my breakfast.....
