How does one do this? My fork has Ishiwata impressed into it, and below that "1" and then a "." and then "J" above those is the circular logo, looks like an SIJ at an angle? I am wondering if there are any other ways to tell if you have 022 019 etc? I have searched but did not find then specifically. Thanks.
Stop reading my posts!
JIS is just the Japanese Industrial Standards organization, means that the manufacturer complies with those standards. As far as ID-ing a tubeset without a decal present: the best you can do is research the specs for your specific frame (search old catalog scans at bulgier.net for example) or try comparing the weight of yours to a known Ishiwata frame of the same size.
