This is truly one of my ultra grail bikes. To complete my Masi collection. It is too small for me so my lust is partially dulled. I am sure others can do just as well but I can certainly fill you in on 60s Campy. NR showed up in '67. I think a '69 NR rear derailleur would be the plain "PATENT" with no date. There is more variation in front derailleurs in that time period than rear derailleurs. The '69 catalog shows the front derailleur with the cable stop integrated into the clamp. You don't really need the cable stop with the clamp on the bike now but I think that is all you could get in 69. You can get a clamp with a cable stop instead of a cable guide to work with the cable stop on the FD. I assume it had Universal 68s? They are not super hard to come by and aren't too pricey but you may have to look around for awhile. I picked up a NOS set for my '70 Windor Pro project and I don't think they were super expensive. The levers and hoods can be a bit harder to find than the calipers in my experience. Glad to offer any help I can. I am sure others more knowledgeable than me will correct anything I said wrong above
