Stromberg Carlson 1250 switch hook help

[allnumbedup]

I am restoring a bakelite SC 1250 manual wall phone.  It has a metal "L" shaped flange that covers the top surface of the cradle between the two stainless buttons that engage the switch hook. When I got the phone this piece fell with gravity but could be clicked up and down. I reinstalled it as shown and with the tension spring in postion against the back of the bakelite shell ---it clicks and holds its place against gravity but does nothing with the switch hook. This metal part has a spring that is wrapped around a pin that rests against the body of the phone in front of the switchhook so this piece pivots on this pin but does not actually move up and down--just tilts.  The actual switch hook has a similar spring on a pin and the buttons depress a part that pivots to break contact while the sprng holds it in contact otherwise. The piece of the switch hook that the buttons hit has a slit in it but the tension wire on the metal L shaped piece doesn't seem like it reaches there or could be placed anywhere to move the switch hook.  I have included a cross section diagragm of this piece labeled 42910 on page 76 in Joe Uzel's book. I also found reference to a two step hookwsitch on a 1250 here:
WDS's SC 1250

I do not this this is a two step switch though. Any ideas as to if I am missing something here? Could it be a 'blank' or maybe a signal switch that relies on a clicking vibration to the operator?

I do not this this is a two step switch though.

ISTR that any 1243 or 1250 could be modified for 2-step switch hook. When not modified, the "Stromberg-Carlson" bar could be pushed down, and it would spring back, but it served no purpose.

The changes in wiring are shown in wds's post that you referenced. I attached part of one of his photos.

There also had to be a mechanical change, which is not shown on the instruction sheet. Maybe you had to bend the narrow metal piece that is parallel to the rest of the bar?

My SC 1250 is wired as described in option one on the paper schematic found inside this phone and on TCI here:

SC 1250 Wiring Diagram

I just noticed this schematic says in note 3 "bend the tab on nameplate lever inward" to convert to a two step hookswitch. I think a tab lying parrallel to the outside part of the nameplate would mechanically work on the second set of switches. So I think popular1 is 100% correct.  I think the strip that is  underneath the tension spring in second picture above is there to be bent at a right angle to do so.  It has never been bent, so I left it as a standard single hookswitch.

The original photo of the phone when I purchased it is pictured below with the handset laid down incorrectly on the phone. I finished the phone by replacing the toasted "koiled cord" with a super fat insulated microphone cord from the 1960's, reusing the original restraints.  Not every phone design would look good with such a beefy cord.  I made a new dial blank card copied from the original to which I added a SC logo and color.  I could not help but think of the "bat mobile" while polishing this art deco styled SC model.

It's a good thing that St. Carl. put the paperwork in each phone. Otherwise, how do you know which version you have?

Note that on the diagram that you posted, it says to "move blue of hookswitch to 10." The instructions I copied from wds's post says "move blue lead of hook switch from 4 to 9."

Perhaps they used different networks in different years?

The early North *H6 sets were wired differently from the later ones, but the later wiring was an improvement. Both versions usually had WE 101A induction coils, WE HA1 receiver units, and WE F1 transmitter units.
