Acme TR-83 valve stems.

[Wick]

I bought a box of prewar Bicycle parts. I found a small case of valve stems with the stuff. 5 Acme TR 83 valve stems. I knew right away what they were!The only information I can find is in the Judging Standards. Pretty sure these are nos.How rare are these Stems?
Thanks Wick

Very Rare, But so are the covers that go over them..

[Wick]

I have the covers on 4 of them.

nice find, are the covers machined out of solid brass, or are they pressed like the Schrader covers. the originals are pressed. the original covers are hard to come by.

[Wick]

Just looked,the covers are Brass.

Wick take a picture looking down from the top. I was thinking about the Dill covers that are pressed. your covers could be original. I will post a picture in the morning of the set of NOS ones I have.

As mentioned, the dust covers are more rare than the stems. The lettering on them should be very faint as typical of Acme stems. I have probably three sets of NOS Acme stems but not enough dust covers to make complete stems. Nice find.

Hope this helps.

Wick I can`t tell by the picture and I could not get a good close up of mine. but on the top side of the rim nut there should be a little detail that fallows around the hex nut. like and extra line.

Here are a couple of pictures of original Acme stems with original dust covers. You can also see the knurled core remover and cap. These dust covers have more rounded edges as well as the faint lines in the vertical flutes.

I'll have them with me at Hershey if anyone wants to look and tell me more about what they are.
Thanks
