brass valves, fuel nozzle...

[mope540]

a pair of brass valves recovered from an old home site. is the one on top by chance a keg/barrel tap??
also found the fuel nozzle on an old farm site. looking for any clues to its age, any value, etc.

thanks for any info!!!

The top one looks like a acetylene gas type valve, but a can't see the other end. On the bottom one KC could stand for the city. Frank
