This contained a Ranger typewriter, model Elite.
No markings on origin or manufacturer anywhere, two small holes but no type-plate on the backplate. Nevertheless it clearly is an Optima produced Elite based on the original '33 Olympia design. (Many thanks to Nick's great write-up on Optima's.) Spruced up with some olive drab crinkle paint to make it look '52. And as further modernization the control levers that were chrome on the pre-war Olympia are now blackened with bakelite knobs.
Likely branded as 'Ranger' to hide its Erfurt, Germany origins, as also described on Scott's item on 'Anglicised' Schreibmaschinen. Nevertheless the 'Elite' decal is the regular Optima type and includes the Optima company logo.
Taking the machine out of the case, putting in paper and it typed away very decently already. Dutch keyboard.
(Not used to typing with an actual 'ij' key, obviously.) Also typing was not helped by the ribbon having been threaded wrong through the vibrator. This wrong way round it snags on the type-guide at avery shifted character. (Thank you for the clear images that made me realize the cause of snagging.)
