Unfortunately, due to this show as stated, being partially lost media and being very hard to track/find information about. Episodes especially the majority of english dubs are hard to find, thankfully however that doesn't mean all of the show has been scrubbed off the earth as there exists a german, unofficial russian overlayed dub and possibly an existing amount of english episodes still out there of the show.
So far only the full german and russian overlayed dubs (with the exception of the russian dubbed last episode) have been found and put in a drive and soon be uploaded to youtube for archival.
