I guess my theory is that this is correctly decaled--a 1987 330 Elance. The dropouts, head badge, and SN all support this conclusion. Badge style changed for 88 models.

The TT remains 60cm, which means that at least in the case of some frames (perhaps related to production in the Merida factory), the catalog spec (585mm) is incorrect.

Can anyone help me determine whether this is more likely a True Temper or 531 main triangle?
