TRIGGERED II: the sequel
Let's take a look at two main things here: the triggers identified as "35" coded and used on late "dou" rifles, and sintetered or "pressed metal" triggers.
First let's look at a few examples. Here we have a grouping of triggers and a late blocky sear. The left three triggers are "35" triggers and the right most trigger is a very similar "e" coded Köhler trigger. Note that there are two different sizes of number stampings for the "35" triggers: the left two are small 35's and the right is larger. The "e" trigger is, as usual, marked on the other side, this side is blank.
Clearly "35" is a manufacturer code, as yet unknown as to what the company that made them was, but as Kriegsmodell III says, and as you can see here, enough exist to be sure it's a code. Here is a closer look at the "35" markings.
Here is the opposite side of the Köhler and two of the "35" triggers. Same orientation as the other pictures, without the left trigger/sear.
Now the following is based on information found on pages 17-21 and 36-37 of Kriegsmodell III, along with my own interpretations and is something I have not seen elsewhere. I think that late war sintered or pressed metal triggers exist and are identifiable. On page 18, point #12 covers the existence and adoption of sintered triggers, and gives a hint as to their identification. "After machine forming the actual trigger release area, the area will be polished and radius points finalized."
Military K98 triggers are two stage triggers, so there are two engagement surfaces on the top of the sear. Look at the following picture. On the left is a fairly common "e" Köhler trigger, on the right an "s" marked older trigger. Note the difference in the surfaces that engage the flat underside of the receiver, and which contact causes the rear of the sear to drop and allow the cocking piece to move forward due to compression of the firing pin spring.
Clearly, these surfaces reached their final configuration by different machining methods. The left trigger seems to represent "machine forming the actual trigger release area". This configuration is seen on late "e" and "35" triggers, along with the next difference. There is a change to the contour of the front of the trigger as well. On the left is a late setup and on the right an earlier trigger/sear. Note the shape as indicated by my lines in the area indicated. Also, look back at the pictures above where the sear engagement areas are circled and you can clearly see the semi-circular arc in the front face of the late style trigger.
It is my contention that these style triggers are made with the sintering process, as mentioned in the Oberndorf documents quoted in Kriegsmodell III. The process lends itself quite well to objects like the sear and trigger, and also to the front band for the stock. Here is an excellent combination of two short videos to explain exactly how the sintering process works.

In this final photo, we can then see the changes more clearly, with the later style setup on the left. Note the blocky fronted sear (more on those coming in another post) as well as the trigger differences: the different top shapes, and the different front shapes on the vertical shaft of the trigger. Of course none of these things are really detectable with the stock on the rifle, but I think the manufacturing difference and resultant different shapes are worth noting.
I also think that these type of changes help identify later applied parts, whether by repair depots or otherwise.

All else seemed pretty uniform with markings and proofs. All of the pins had both the "e" and e/221 save for just one with a "q" and e/221.
All the shrouds were identical save for 3 of them that all had both a tiny "R" and "K" on the inside shroud lip.
Seeing the shrouds are all "e" marked from Herman Kohler Mfg. I am guessing the "K" is for Kohler, but the "R" is a mystery. As a side note my oldest son thinks I am a little "off" studying these tiny markings and differences and was just blasting "too much time on my hands, by Styx" on the Bose system...lol.
... all but one with the less refined, blocky sear. The sears with "a" and e/18's, e/221, e/46, "o" and "e" are off 1939/337 rifles.
