There are a few different wiring schemes used for these over the years

Hi Greg-
The reason there were several different wiring diagrams is because there were about a dozen types manufactured for various service requirements:

295A Wood-For direct, two-party selective or four-
party semi-selective service. This may be used
with the No. 7 type coin collector on single
party lines, or on party lines when code ringing
is employed.
Includes: 1 No. 8-AG (1000-ohm biased) ring-
er, 1 No. 21-D condenser, 1 No.20 induction
coil.

295-AA Wood-For local battery talking and central
battery signaling service.
Includes: 1 No. 8-AG (1000 ohm biased ring-
er, 1 No. 21-D condenser, 1 No. 13 induction
coil.

295-AC Wood- For extension service to a main telephone
se t on a direct two-party selective o r four-
party semi-selective system. No ringer is fur•
nished .
Includes: 1 No.21-D condenser, 1 No.20 in-
duction coil.

295-AM Wood- For central battery harmonic selective
signaling service.
Includes: 1 No. 41-SG (460-obm) ringer, 1 No.
21-D condenser. 1 No. 20 induction coil.

295-AN Wood-For central battery harmonic selective
signaling service
Includes: 1 No. 4l-TG (460-ohm) ringer, 1 No.
21-D condenser, 1 No. 20 induction coil.

295-AP Wood- For central battery harmonic selective
signaling service.
Includes : 1 No. 41-UG (460-obm) ringer, 1 No.
21-D condenser, 1 No. 20 induction coil.

295-AR Wood- For central battery harmonic selective
signaling service.
Includes: 1 No.41-RG (1800-ohm) ringer, 1 No.
21-D condenser, 1 No. 20 induction coil.

295-AT Wood- For series service on a single, two-party
selective or four-party semi-selective system.
Includes: 1 No.8-AG (1000-ohm biased) ring-
er, 1 No. 21-F condenser.

295-AW Wood- For series harmonic selective signaling
service.
Includes: 1 No.4l-SG (460-ohm) ringer, 1 No.
21-F condenser.

295-AY Wood- For series harmonic selective signaling
service.
Includes: 1 No.41-TG (460-ohm) ringer. 1 No.
21-F condenser.

295-BA Wood- For series harmonic selective signaling
service .
Includes: 1 No.41-UG (460•ohm) ringer, 1 No.
21-F condenser.

295-BB Wood- For series harmonic selective signaling
service.
Includes: 1 No. 41-RG (1800-ohm) ringer, 1
No. 21-F condenser.

 To further complicate matters, Western Electric used two different markings that they designated as Old-Style and New-Style on their boxes. 

Here are two examples:

Most of the 295 types are covered here:

http://www.classicrotaryphones.com/forum/index.php?topic=9359.0

The majority are party line sets with 4 different models for each configuration.

When I said " a few" I really meant the three different types found on 295As:

The "Early version" or "Old-style" was found roughly on sets with patent dates stamped in the sides.
The "Later Version" or "New-Style" was found on sets with block-style script on the decals
The latest version has a picture of a candlestick similar to the ones found on 334s and is found on sets with the Hawthorne script decals (roughly).  I do not have a copy of that schematic, and I am not sure if the basic wiring differs from the previous version.

Greg, could you repost the "later version" diagram? Just seeing a box with an X.

It is linked to a picture in the same thread as the other one, and I can see it, so I'm not sure what is going on.

 Here is another 295 wiring diagram for l.b. service

In case anyone finds this useful, here are pictures of a 295A box I just got, including the wiring diagram affixed to the inside.  It looks like this box was modified at least once by WE, because the diagram is pasted over another one, and it appears the technician scribbled notes on it. Also, the back was previously labeled "TYPE xxx" where the "xxx" whatever it was has been gouged out, above the stamp "295A." The box is oak.

I'm going to use this with my 50AL saved from being a desk lamp...

Not only that, but on yours, the terminals that are normally screwed to the wood sides have all been moved to a phenol terminal board that sits on top of the condenser.  The terminal board looks like one from a 534A

Oyang, your subset may have originally been a 212-type. Note the "2  4  L2" original locations stamped in the bottom panel.

Re the 295A:
The original method of designating terminals for the connection of the telephone was later updated to correspond to tracer colors of the desk stand cord:
OLD:       NEW:
L2            Y (yellow)
4              GN (green)
2              R (red)

That makes sense; thanks. Looks like Western Electric was pretty frugal in recycling its equipment.

The terminal board only has 6 terminals, while the wiring diagram has 7 (R, GN, Y, L1, GND, L2, C).  In the diagram, however, Y is linked to L2.  Am I correct in assuming I can use one terminal as L2/Y, i.e. hook up the "yellow wire" from the stand directly to L2? 

Also just to double check, I assume this wiring diagram will work for a 50AL?

Many thanks as usual,

Otto
