Veteran Motosacoche riding a long distance trial

I know nothing about this pair of pictures and would love to know more. Looks like a long distance trial from the veteran era possibly a MCC one or it could be the Scottish Six Days. My only guess as to the machine would be that it is a Motosacoche. Seems like he's adding slightly more than light pedal assistance to aid his machine up the hill.

There's an interesting article about Motosacoche on Andrew Pattle's moped archive.

Heavy pedal assistance!
