What do I have, Brass candle stick phone

[Logan1]

Western electric brass, what do I have here, before I put on eBay. Says 20 AL  on perch with line thought it.

Appears to be a "conversion" done at one of the Western Electric Repair Shops. The original model number -- 20AL -- was for a manual (non-dial) telephone. Look for the new model number on the back or side of the "perch." It is probably marked 50AL, 51AL, or 151AL.

Did not see any other numbers on perch,

[poplar1]

In that case, we would need to see the inside parts: the wire "harness" can have 3, 4, or 5 conductors. There may be 0, 1, or 2 terminal blocks in the base. The hook switch may have 3 or 4 leaves.

Harness:
3-conductor = 51-AL
4-          = 50-AL
5-          = 151-AL

Terminal blocks -- as originally configured:

0           = 50-AL
1 (R and GN)= 51-AL
2 (R/GN + Y/RR = 151-AL

Rack (hook switch):

3 leaves = 50-AL or 51-AL
4 leaves = 151-AL

Pictures would be helpful.

It appears that the dial was converted from a #2.

It appears that the dial was converted from a #2.

I assume you based that observation on the screw hole in the disk case (red circle).

The only other image of the other side of the finger stop is too dark to see the serving hold (yellow circle).

Am image taken straight on to the finger stop would show both holes and any stamped characters on the stop itself.

And as asked for by poplar1, images of the inside of the base are needed.

The re-build also included changing the original transmitter to a bulldog.

Looks might be a 51AL

poplar1, would a refurb shop upgrade the dial and transmitter and NOT upgrade the hook switch to anti-side tone?

I don't have a definite answer.

Transmitter could have been updated in the field.

Even 151-ALs are sometimes found with 2A dials, if already equipped at the time of the conversion, probably because there was no reason to replace them. It's possible that this was a manual (non-dial) phone, and that the dial was added later.

Is there a brass strap between BB and R on the back of the dial? If so, that's a good sign that the dial wasn't installed by the antique dealer or whoever removed the original black paint.

Also, there are two WR-(War Restrictions) BSPs on blue stock showing how to connect a sidetone desk stand (candlestick phone) to an anti-sidetone subset. This implies that there was a shortage of new parts needed to convert a 51-AL (sidetone) to a 151-AL (anti-sidetone) during the 1941-1945 years.

Can you post pictures of the inside base and of the hook switch?

Also, a 151-AL should have a 4-conductor cord (Red, Green, Yellow + Black).
