These are a couple of very nice old fire truck collectible s. The Akron B rass company valve is original and it's been pulled from an old firetruck. It seems to operate well currently, but it hasn't been test ed.
It has quite a bit of information on it, which is photographed f or your reference. The housing itself is in good condition with no cracks or hairlines that I noticed. Please check the photos closely for complete details.
