Swell looking 'Jungle Carbine' Whig!!!

Your father's $17.50 investment will bring you many happy returns.

Interesting, first time I've seen a three digit number.

My Fazakerley is serial number O5327 dated 7/45.

Like Littlejohn had mentioned...the numbering system for Fazakerley made no5s began with A1 to A9999, B1 to B9999 and so forth.  Letters omitted were I and J.

One of my references does mention a B.S.A. (M47C) .22 trials rifle that had a T1 prefix (Only 100 were made).
