Possible Nintama Rantaro Pilot Episode from Early 90's?

Well. ha ha! i might start something here guys? Just a very hard search! you know about that one NHK anime from 1993 called
Nintama Rantaro? Right.... no? let me tell you. This is a anime focusing on 3 boys: Rantaro, Kirimaru & Shinbee (or Shinbei)
and they go on cool Adventures! The series is available on Nyaa.si (so check it out, but you need uTorrent to download the files).
Anyways? not only Nintama Rantaro is rare to find on YouTube (only Hindi dub exists) >:-( , but. a Possible Pilot Episode
produced in the Early 90's? (Possibly 1991/92?), if you did not know? it might have been animated by Shin-ei Animation
(the Same company that made Doraemon, Crayon Shinchan, Q-Taro & Perman) & TMS Entertainment (The same company that made
Lets Go! Anpanman, Q-Taro (1965/1971), Perman (1966), Sonic X and Overseas like Inspector Gadget for DIC), not Ajia-do Animation Works? its Possible that the Pilot exists online?

So, heres Episode 1 in 480p (ha ha!):

(The thumbnail is an asshole?, Sorry for a sexual joke in this thread. though that will be a joke to you?)
