It Looks a lot like the bike I bought my wife in 1984 The brakes are Shimano. The crank is possibly a Suguino or SR I no longer have that crank on her bike The Frame is straight Guage Hi-Mn Steel I put an SR Laprade seat post to replace the cheap post that came on the bike just like this one. Chrome Forks are original. I've been upgrading my wifes bike since I bought it
