The London and Snowdon maps are quite common, but the Canterbury and Norwich are really quite a lot rarer. They hardey ever get onto eBay.  The Birmingham one, I have never seen listed.

So - I have on offer, a good version of the Snowdon map, dated 1961 (but I believe this version was released in 1963, as the OS logo is in a square box on the front cover - and that didn't start until then)

Please refer to the images as they are 99% of the description - if in doubt, please ask before you buy, as I no longer accept returns.

Marks and writing on the cover, but it would seem that there are no rips,, but the map itself is in excellent condition

Thanks for looking, and please see my other OS maps that I am selling, as I thin out my collection.
