Found in an Edinburgh charity shop, so while it’s not impossible, it’s unlikely.
EDIT: Also, an NTSC signal on a plain PAL TV would be black and white (not even false colours) even if you got an otherwise stable picture.
It’s easy to forget, but these old systems didn’t connect to the TV with composite RCA connectors, but via RF. So we’re not just dealing with straight PAL, but with PAL over a broadcast system. Scotland was using PAL-I for broadcast, while Poland seems to have used a combination of PAL-D and PAL-K. Differences in channel ranges and bandwidths, and sound channel offsets, could make it difficult to tune a TV set designed for one system to a signal from another, especially if it’s a more modern set designed for automatic operation, as OP’s set appears to be.
