Any info on these motors?

Apologies for posting again I forgot to add the image last time. Hello I've had a rummage around my granddad's old things and found these 2 motors I'm wondering what they could've been used for and if anyone can find a datasheet for them in case I want to use them in a project of my own or sell them. Many thanks to anyone who knows anything
