For The Great Britain Stamp And Cancel Fancier

Nice acquisition. I posted some time ago a consular stamp too (on a KGV thread)- mine is a 2 shillings, found nothing about. Here are some cancellation:



First is WC/12 (or WG?- if it`s WC, I wonder if there is an OO too somewhere? or maybe I should check my US stamps too?)
Second is in fact the reason for posting- it reads ...NGLAS/8/DE31/.9/DUBLIN? or DUBLILL?- any info?
Rest is 104, 105, 498, 65, 75.

There is a Finglas, County Dublin. http://www.dublintourist.com/towns/finglas/
The "nglas" suggests a Gaelic origin, so Dublin seems likely. "glas" means "grey", and is not uncommon in placenames. I couldn't find a Kinglas or a Dunglas, which were my first guesses.

Thanks Stampgal! Solved, Finglas.
