what type of hangar

What type of flying boat hangar? see attached

The photograph appears to be of a 1934 Type 'C' Hangar. Most flying boat base had the Type 'F' Hangar with side opening doors.

MOD published a hangar identification document some years ago. It can be found on-line but here is a typical link:

If it's for flying boats, I'm going to guess Type B at Pembroke Dock.

That would have been my guess too. I note the picture filename is hangarrhu_
I'm not sure what sheds Helensburgh / Rhu had, though a photo on this page looks similar to the OP picture.

Rhu/Helensburgh is in Robin's patch!

At 2 o'clock on the edge of the image cab be seen a multi-pitch structure which, I think, is the RAF Rhu hangar. The image is dated 1949

Well spotted. The roof structure is identical to the two remaining hangars at Pembroke Dock. There is also something like a Bellman / T2 alongside.

I can;t find anything on any on-line maps, and am not entirely sure where the site is exactly.

The RAF Rhu slipway and hangarage was located here:

In Robin's photograph it would appear that the aircraft is sitting at the top end of the slipway with the hangar behind.

Rhu was a Marine Aircraft Experimental Establishment which is probably why that aircraft prototype was there. Since 'B' Type hangars featured at other flying boat bases such as Pembroke Dock it would be a fair assumption that the Rhu hangar too was a 'B' but too little detail to be conclusive.

On reflection, the profile in the photograph could be that of a 1934 pattern Type 'C' or a Type 'B'. Although the Rhu site dates back to WW1, when was the subject hangar erected? If it was not until 1938/39 why build a 1934 pattern 'C'? Was open door width and internal capacity a main factor? Operational aircraft in numbers would have been moored out on the trots coming ashore only for maintenance and repair whereas 'one-off' prototypes might be hangared for safety and security (thou shalt not see) except when out for flight. Just thoughts.
