The serialnumber is E94040397 its also marked with a diamond with an E or an F inside and directly after SB on the bottom tube.
It is an 1 1/8 inch ahead set and was orginally equipt with a mixture of Shimano LX and DX when I bought it. So I guess from the serialnumber its a 94 and some of the parts where not orginal.
Which would be right with the cranks were LX M563 which were made 94-96.
Dont think the bike is worth anything more then the parts but I really like it and are curious. In comparision to some other bikes I have bought after finding this site 3 years ago it was almost free. Gone from zero to 15 retrobikes in three years....
