I have the same exact bike, I noticed from your picture that your crank set is not the same as the one I have... I hav a sugino VP crank set... what does that one have ? i see a chainring guard... mine didn't have one..
I picked up my bike @ a thrift store for $ 37.99 and I converted it to fixed gear... so I ditched all of the components except for the front brake and one lever.
This bike is really nice and I cleaned and re-packed all of the bearings including the BB which I had to buy a crank puller tool from ebay for $ 14 to get them off...
Also, one thing to note is that you will have trouble finding tires of the high quality race variety that are availale due to the older wheel size...
My araya wheels are 27 x 1 1/4 size... most newer tires and hardware are made for 700c wheels ! OUCH.
I guessed that mine was made in 1986 based on the serial # info...
So good luck with your bike !
