I've seen a few Daccordi's; never in my size unfortunately. A nice looking, classic steel bike with unusually good paint & detail. Your's may just need a new chain. Dura Ace 8 speed with DT shifters also very fine. $400.00 is a very realistic price for a nice rust-free Daccordi, and yours has the added value of 50th Anniversary decals & possibly pantographing.
