Can you indentify my roof tile

Can anyone identify these... there's no makers mark on the back unfortunately:

Marley 'Anglia'?
Quite possibly the most horrendous tile to lay.

could be Anglia, Anglia plus (now) OR its a redland 52 They are bigger than Anglia and hard to find. not interchangeable.
If you post the dimensions then either can be eliminated as the 52 is quite a lot bigger

I'll measure one when I get back later and let you know. The house was built in 1963 and I think they're still the original tile, if that gives any clues.

The reason I ask is that I'm building an extension that'll have a roof that's linked to the existing roof by two dry GRP valleys. So I suppose they only actually need to look the same, rather than actually being the same. My intention was to get some identical ones from a reclaim yard, though. What would you suggest as the most similar 'best' type?

Best type.. i personally prefer Redland products.
In this case its irrelevant I would think Anglia will be the easiest to find.
