Keeping on the theme of turning the clock back further and further, we're now into the Quarter Inch Third Edition.
The Third Series is, quite frankly, a confusing mess. It's in two halves, the original sheets and the so-called "New Series". There's two different sets of sheetlines. However, the Third Edition New Series is also the first set of "standard" OS sheets to have road numbers printed on them, so it's important for us to have them. As a "bonus sheet", a Special Sheet from 1929, that of "South Central" has been added, even though it's actually a member of the older series without road numbers. It's still really useful to take a look at the road network of the area though!
So, there's a massive bunch of
21 maps just been uploaded to SABRE Maps from between 1929 and 1934 inclusive; and they're also all available on the
SABRE Maps Sheetfinder.
