-Comment: As announced I found one clip on the Swedish channel. Today it turned out that this is a series with at least 9 episides (IMDb known 3). And the clip is probably episode 2. At least also in ep 6 maybe in all episodes. Maybe also a girl?

Boy in dark blue and also faded bibs. 

Available on the Swedish broadcaster but inside Sweden only. On archive.org there are I think only screenshots. Pic from another channel (PB-SSE), there are ep 2 and 5. 2 is pictured, colors I made a bit brighter. Are even darker. Boy is kneeing. No scenes found in ep 5.

English title: Inventor's Coat.

For now rating ~4 or less.
