I have a line on a vintage bike I suspect might be a pre-war Phillips roadster, and was wondering if anyone has any information about their serial number ranges. I know I can probably date it from the hub if it is a Sturmey-Archer product and the approximate age of the rest of the bike. but I cannot tell from the pics if it has one or some other hub of the era, or if it's been replaced or modified. Did they stamp on the lower left dropout like they did during the BCCI era?
Since it's a roadster, it might have bolted stays, anyway...

Can anyone point me toward this info?

Thanks so much,

P.S. yes, there will be pictures if I decide to get it.
