Ok, I know there are a couple of you out there who know something about this.
If Pogliaghi frame with a serial number in the 9000s was made in 1970, when would a frame with a serial number in the 3000s or 4000s have been made?
I am a tad confused about quantity of production coming out of that shop in the 60s. And it would be nice to get a better bead on how the serial numbers correspond to year of manufacture. Clearly my first hack at this was WAY off.
Thanks.
