Thank you for the reply!
And so it becomes interesting
. As you mentioned when I tried to post pictures they were added to a gallery, hopefully it is open to everyone. My original conclusion that the bike came from the early 70's is based on a comment I received by a bike mechanic. He mentioned that the method of engraving/stamping the B's (sorry I don't know the correct terminology), for example where the seat stays connect to the seat post, was changed after 1975 dating the bike to a time before that.
If I may ask, what is your reasoning for that the bike most likely is a 1986 model?
