Rarity of Blue Point Oxy Acet Regulators??

[dimwittedmoose51]

I have polished up an older pair of Blue Point Oxy-Acetylene regulators and wondered how old and perhaps how rare they might be? Each one has a gauge that's been either dropped or something fell on it to pucker the dial reading ever so slightly. Figuring these are more of a collector's time than "workers", the damage couldn't have been too bad as the plastic lenses both screw on and off easily and the housing doesn't appear to be deformed. Thanks in advance for the help.

BTW., these will likely be going on ebay soon along with another Blue point wrench auction of mostly older series stuff, if anyone is interested. I usually start stuff out at $5, so the market determines price, not me. My seller ID is the same as my Snap on handle.
