I am trying to figure out how old an Alan frame is from its serial number. I did some Googling, but didn't find anything useful. Do any of you know the secret or know of a web resource? The number in question is 439324.

P.S. Would the Guerciotti branded ones have had a different serial number scheme? They seem to be as or even more common than the plain Alan versions...
