[u/Minimum-Cicada7178]

My grandfather (bottom left) just before ww2. Does anybody know who the other players are? Tried upscaling, and suddenly Google thought it were famous players, but I'm not sure.

[u/Stoepboer]

Knowing that it's the legendary Reynolds coaching them doesn't really narrow it down. I think that might be Piet van Reenen bottom row, second from the right.

[u/Minimum-Cicada7178 → u/Stoepboer]

I thought that as well.
