What is this tongue and groove called?

Hello,

I need to add a couple of boards to my panel in the stairs, but I don't know what this is called. I would guess it was installed in the 70s.

Panels like that exist in as many variations as there were small sawmills and planing mills in the past. There is no standard for such things, everyone had their own, and what is fairly similar is what the large companies have planed and distribute via lumberyards. But if it's older, it's probably just as bad anyway...........

Thanks for the reply!

I'll just have to search and see what looks most similar

My panel is 135 mm wide and unfortunately it doesn't seem to be a standard measurement today. At K-Rauta they only had 95 or 120 mm wide
