Don,
That's a model "99 BIS" NM [nouveau modele] from the early 80s. Smallest chainring went down to 28t and up to 54t for the largest. It was a less expensive model, intended for easing climbs for the recreational rider, but could also be used as a double crankset. This model was only available in 170 mm length arms. Outer bolt holes on larger rings allowed a chain protector ring to be added if required. Also was available without perforated rings as simply "mod. 99".
The model "105" ("105 BIS" with drilled rings) was the double crankset with a "Star" spyder similar to the earlier model 93 "star". 37-56t (122 BCD)
Model "104" looked more modern - like Nuovo Record, but with 38- 53t (122 BCD)
Model 106 looked like a Campy Super Record, complete with cut-out webs on the outer chainrings 42-56t (144 BCD).
The 106 was their top pro-style model in the early 80s and weighed over 100 grams less than the double chainring version of the Mod 99 set now at auction... in spite of the drillium rings.
