What type of flathead water pumps are these?

Just wondering what type of water pumps I have on my flathead. They look a ton different than what im used to seeing.

Im putting on new water pumps so if anyone needs these they are for sale.

 

look like early 50's passenger car to me.

 

Mercury with narrow Ford pulleys

 

Are they worth anything?

 

probably worth $10-15 each as cores. they might be good too, never know till you run em. modern rebuilts available for $85 each or so. stock (nos) available for $65-75 or so at napa, etc.. JMHO

 

They fit 1949-51 Mercurys. The narrow pulleys make them for the 50-51 s.

 

Thanks guys for the info!
