Iwatsu SS-5321 oscilloscope literature, manuals, any INFO!

[MrAngry]

I just picked up this scope and can't find anything other than basic info like it's 250mhz 3 ch, yeah uh that's right on the front of it. What I need is user & service manuals, or possible cross reference info to other scopes that were marketed in the U.S. that were essentially the same as it. I found a link to a news atricle showing that lecroy had a long time affiliation with iwastsu but found nothing more. By appearance I'd guess that iwastsu, kikusui, & leader scopes of the era were being made by the same manufacturer can anyone confirm this? I haven't heard back from iwatsu japan, the us division is telecom products only

Any luck finding a manual? I need one, too.
