Sorry Rattus - my fault for not being clear. What I meant was where are the rows on the map. Section L contains rows LA-LLL [according to the key on the map] - so where do I find rows LT and LS?
Ah, I see! Well, that document is still relevant. Keep going down past LT and you end up with LZ at the top of page 25, which then leads straight into LLA and continues to LLL on the final page (40).
So that Section L on the map is the one you need. The key - and indeed the whole lettering scheme - is somewhat illogical, but the document shows how it works.
In summary, if I'm interpreting correctly: Section L is comprised of two-letter row codes running from LA to LZ, followed 'sequentially' by three letter row codes from LLA to LLL.
