VIE's subhelp java applet

[Fenix]

Back in the day, there were a handful of java applets available from the official SubSpace website. 

• subcredits: a small vertically scrolling text widget against a star field. Was seen on the official site's landing page.
• subships: a fun little visual banner that had the original 5 ships (warbird, javelin, spider, leviathan, and nightwasp) moving back and forth across the canvas against a star field.
• subhelp: ???

I've found copies of the first two applets and have even gotten them working in an old applet viewer. Eventually I plan to try porting them to javascript. However I have not been able to find any copies of the subhelp.class applet.

Does anyone remember what this applet originally did and what it looked like? 

Given the context of originally being on the website's "Online Help" page, I assume it was some kind of visual reference guide. Furthermore, by inspecting the html of the page (courtesy of the internet archive), I can see that the applet canvas was defined to be 640x480 in size. This stands out to me because the original client's quick help screen was pretty similar in size at 626x489. So I wonder if maybe this applet was just a web version of the client's help screen? Can anyone who remembers the old SS website confirm?
