I'd have to see an image of those numbers so I know where they came from (25 G 00 and somewhere else it writes A3) Jeffery, as they may just be part numbers.
I've only seen the Victa codes up to 1991 so the AC052 AA90 on the air cleaner cap doesn't look original ,someone has replaced it as it's from a Commando , should be something like AK060 UK90 .
