Need help identifying Radiator thermostatic trap

Hello all!

I have been searching all over for this type of trap on my radiators so I can see if cage replacements are available.  They are 2-pipe style radiators.  The only identifiable text on the trap is the logo itself.  The logo is round and on the top it says, “TRADE” and on the bottom it says, “MARK”.  In the middle it looks to be a merging of the letters “O” and “E”.  I’ve tried looking up this “OE” company with no luck.  My first assumption was that the “OE” stood for “Original Equipment”, but I have no idea.  If any of you subject matter experts could give me any ideas, replacement options, or info, I’d greatly appreciate it.

a little background on my house:

It was built in Wisconsin in 1896.  I counted 16 radiators, supplying heat to 3200 sqft.  I believe it was originally a vapor-style system that has been modified to a regular steam system.  When I bought the house 4 months ago it had a Burnham IN10 which literally melted down a week after I bought the place.  It has been replaced with a new Burnham Independence IN10.  I’ll be making a future post in the future showing the new near boiler piping which i believe needs some changes…but I’ll save that info for a new post.

    I'm pretty sure O-E was located in Milwaukee, just like Milvaco and Sterling, which still are.

    One way to get familiar something you know nothing about is to ask a really smart person a really stupid question
