Not forged, but they look hand cut. And the workmanship is very nice, even where the dropouts join. I'd guess a 50's English bike (TDC is Cross, later Cross and Sons, I think. A good English brand). If you clean the freewheel, you'll probably see TDC as well. It looks amazingly original. 36/32 spokes front/rear?
what brand is the brake? the headset? the hubs?
