Hi Fred, Glad to see another Mirella is being rescued.
The Mirella brand was made by Leri using their own type seamless tubing AQ-35. They had a sticker located on the downtube above the shifters with this info. A search of the archives for "LERI" returns a few posts most from 8 years ago. There you will find an interesting read on a letter, posted courtesy of a fellow list member, about the history of Leri as a carriage builder written by the granddaughter of the founder.
About your particular build. If you think the frame is from the early '70's then I can offer how mine is equipped. I know only from photos of others that Leri did make component changes later on. I have an old photo copy of the ad sheet with sort of a build spec for a Mirella which matches up to my year 1973. If you would like copy I can mail one to you, just email me your mailing address.
Mine I had acquired as a complete bike that had been ridden little and suffered only the neglect of time and handling. I think it serves as a accurate reference for components.
Hubs and rims, Nisi Tubular with LF Tipo hubs F&R derailleur Campagnolo Nuovo Record stem and bar, 3TTT Seat post, Campagnolo 2 bolt NR Headset, Campagnolo Gran Sport (maybe NR, not sure of the differences) Crankset, Gran Sport, 3 arm steel with alloy rings, cotterless. brakeset (saving the best for last) center pull Balilla with Balilla levers from the late '50's/60's with the protruding pin quick release. While these brakes can be made to function adequately and in fact are still on my bike which I ride frequently, I would suggest Universal 61's as the better option.
Hope this helps!
