I don't know where I got the idea from, but somewhere along the line I formed the opinion that a single cherry pay out on a Mills started with the Hi-top range. I've had Castle Fronts pointed out to me as Fake/Repro/A lash up of different machines etc. because of a single cherry on the award card.
Over on Facecloth I put forward the above theory regarding a War Eagle and was told "Two cherries is usually before WWII and one cherry pay is after WWII." Now that partly supports it, but I can't find end of production runs, so were the likes of Castle Front/War Eagle and their like still produced after WWII and sported single cherry pay out?
