Monark built, Trophy badged frame. What year?

Plate on BB reads: Model no. 3106, Serial no. A008923. Any help would be appreciated. Thanks

Something looks off on serial. Are you sure it isn't something like A098923X? That would make it a '50 model which seems about right. I'm guessing a base model bike but hard to tell from just a frame. V/r Shawn

Took another look at the serial. I'm sure it's two zeros. The 8 is more likely a 9. A0099231
