1980s

Hi! I just bought this beautiful bicycle at a yard sale at Lago di Como. It has classic 80's looks, ITM bullmoose, a decent lugged frame with some nice details and a mix of Shimano and Ofmega parts. The cranks + shifter suggests that it is an 86 bike but I cannot find any information online...

This North Face advert just turned up on my Facebook feed… can anyone ID the bikes from these photos? Do we reckon mountain bikes with aftermarket drops, or…?
