Earlier Squier Mini guitars (2004) are indicated as a 20.75 inch scale per the 2004 Squier catalog, not than the 22.75 inch scale of the modern Mini. It is also identified as a Bullet series, Affinity model in the 2004 Squier catalog.

I have a Squier Mini with an IS00.... serial number, pre-Affinity series.
So it seems to predate Mini versions 1 & 2. What is this version called?
