This is on a full 900ft spool and is presumably part of a big film.
At the start it fades in to a group of Sheiks in a tent & then goes on with various scenes of Arabs attacking British soldiers, the war office in London etc. Sound stripe down the side but I only have silent 9.5mm projectors.
One actor in Arab dress appears to be English, A bit like Lawrence of Arabia but clearly not

I think you will find this is a film called “Jericho” made in 1937 with Paul Robeson.
Hope that’s of some use although I do stand to be corrected 📽📽📽

Thanks Gwyn, I just looked it up on Grahame Newnhams website & see it was a
5 reeler so X2 on 900ft & I have the second half on one reel. It was likely issued with a different title for cinema release I expect

EDIT: released in the USA as 'Dark Sands'

No problem Vic hope you find the rest

No point really as I only have silent projectors, I'll probably put it on Ebay
