WE 202 D8 handset mount wiring questions

[poplar1]

Searching for "hand telephone sets" in TCI library, I found BSP Section C63.323  from N. Y. Telco. Manh.

              FIG. 6 --  215 Type Hand Telephone Set for Use where
                            2 or More Stations are Connected to a
                            Common Anti-Sidetone Subscriber Set

C63.323 Addendum A from the same company shows the 213:

                            This addendum...covers the connections for 213 Type Hand Telephone Sets, rewired for use where more than one
                             telephone set is to be connected to a single anti-sidetone subscriber set.


                            FIG. 7 --213 Type Hand Telephone Set Rewired

I have not found much in the way of documentation for the D8/215 except for the cording BSP.

I put mounting codes in a couple of BSP descriptions so they are searchable. Try this:

Thanks Paul. All but one of those I  have seen - the one I had not is C63.353 which has a circuit for the Tele 215. This answers the question I posed earlier but introduces a couple more.

1. What is the telephone code for the D8 with the hook latch and its subset?

2. Why is a hook latch added to a D8 and the mounting is still coded D8?

Perhaps because I look for the latch but before now, all the D8s I had come across had hook latches.

I haven't studied this in detail, but recall a discussion about Vern's set.

It's possible that the part stamped D8-A9532 was treated as an option that could be added in the distribution houses as needed  (using a standard "kit of parts"). If so, finding it in a catalog or BSP would be a challenge, as they were generally not marketed -- but only supplied when absolutely "needed."

That strategy was used fairly often for features that were ordered fairly infrequently but often enough that a standard modification was helpful. That saved the cost of creating and inventorying a separate mounting code or model number.

Some of my favorite (later) standard sets that included standard modifications were documented in the April 2018 Singing Wires -- a WE 565 keyset and a 558 wall set that were both modified to include speech amplification, as was done in a 532 set. They expected to place enough amplified desk sets to justify creating a separate model number, but the demand for amplified wall and keysets was much lower. There's a small photo of the modified 558 here:

With a little thought we can probably come up with many other examples. There are several BSPs that list standard modifications implemented with kits of parts and I have several sets in my "study someday" box that have modification codes stamped on the bottom.

Ah yes, I forgot about the number ink-stamped on the cradle plunger.

On sets the appeared on eBay that was not visible so for a long time, I didn't know it was there.

It must be just pure chance that except for this example, every D8 I saw had a hook latch. As I mentioned before, that might be because my radar picks up the hook latch before the ID.

Thanks again Paul.

You're welcome, Jack.

It's still worth retuning the radar for plain (unmodified) D8s to test the theory. We should find more without the latch. More hunting in the BSPs and catalogs won't hurt either.

Thanks for posting this. As noted in another post, there is another use for the D8 for which there is, as yet, no documentation found.
