Hi Mike,
A bit of detective work here. I'm not certain, but the only silver Battle I can recall (or find pics of on a quick search) is the prototype. The 'Aluminium' paint finish, black canopy outline, spit-wood paling fence and roundel type indicate to me that you have a photo of the Battle prototype in the UK somewhere, possibly Hendon at the RAF Display, but if it were it should have a 'new types park' number on the side.
There was essentially only one 'mark' of Battle, the Mk.I, variants being a Belgian export version and the Canadian & British modified trainers. IIRC, Battles were
built camouflaged, and those sent to Australia and Canada would have been sent in camouflage, then repainted into training colours; so silver is an unlikely scheme (unless there was a UK batch built in silver, which I don't think is correct.)
The prototype looked quite different in details originally, but was brought up to Mk.I standard later (still in Aluminium) so it is possible; but not conclusive. I don't think a silver coloured Battle would have appeared in Ontario / Canada, IIRC (and I may be wrong) Canadian Battles were camouflaged or in TT / training yellow / black.
It's possible that the photo owner was given a print of a UK photo, it's not necessary that he was in the UK himself.
In answer to the
actual question it's either a Battle Mk.I or the prototype.
As to the 'Bacchanalian Blonde' anyone who was flying a British aircraft would have had a classical education then, and be familiar with the idea of Greek and Latin as a source of humour. As Kansan and Ken have said, it's not without precedent, and just means drunken (or alcoholic) and given the Barra's propensity to fly badly and to poison its pilots with Carbon Monoxide it may be a comment on the unreliability of the type.
The Hieroglyphics are interesting as they are clearly written to be read, rather than to 'look nice' - the design-work is a 'typeface' that doesn't usually get used for hieroglyphics which tent to be represented in real or pseudo- ancient Egyptian characters.
Hope this helps!
PS I suggest you post the Barra and Battle pics over on the Flypast forum - you might get some interesting further Gen / comment there, and certainly more on the Battle.
