Yes film cores can be hexagonal form.
The Source Book has a drawing showing tube construction, and Rinsey Mills says; At first the radiator cores were of true honeycomb construction but for reasons of economy these were soon substituted for hexagonal film block then, by the mid to late 1920s, interleaf diamond film block.
This would tend to agree with Wyatt who says Austin started fitting their own radiators in mid 1929, this is the style of diamond core which Austin are making in the film.
I am hoping we can find some contemporary literature which confirms the above.
