The LR 109s shown have the Safari Roof. As you said it creates a shade
effect and the heat transfer between the Safari Roof and the LR 109 roof is
mitigated by the dead air space between the Safari Roof and the LR 109
roof.
I had a 109 D with the "Africa Kit" in 1967. No rust. Piteously Slow but
the Tip open windows were a fine feature.
Pensionerd.
