Communicating with the RAF Museum

I’ve been trying to correct some errors in the titling of photos for sale on the RAF Museum photo site via their feedback system(3 attempts) with no success
The items are in the Charles E Brown collection….SAAF DC-2 (2 views)…its actually a BOAC/KLM DC-3(Wright engines) Zilverreiger G-AGBE(ex PH-ARZ) at Bristol Whitchurch about 1942…BOAC DC-7B its actually a DC-7C (thats the model they purchased, significant differences)….British Airways Lockheed 14 G-AFGN is a SUPER Electra (a nitpick, I Know)
Hope this gets through to them…the service on the shots I bought was speedy and free replacement of a print I considered too dark and overcropped no problem
