Someone I know was recently working on a Seiko Bell-Matic and needed a copy of the technical guide and parts lists. There is a version of this readily available online, and while much better than nothing, the quality of the scan is quite poor and omits various information. Consequently I ended up scanning a new copy of the technical guide as well as the JDM 27j and export 17j parts lists. I thought that this may be of use for others as the 4006A Bell-Matics are always a popular model.
