I've found that Raymor labels, at least on glass I've had in the past, tend to include an abbreviation of the manufacturer - so 'KAS' would be Kastrup, for example - and the numbers correlate with pattern numbers used by said manufacturer.
'AVE' might, then, be...? I've not a clue. A.Ve.M. is the only thing that leaps to mind, but I'm sure there are more likely contenders.
