You mentioned the rifles going to ss2 around ‘41 for the bolt and band upgrade, but have you trended when original conversions made that transition or was it sporadic or depot specific?
Not exactly sure I understand the question. The majority of SS Gew conversions were updated, mostly once the Waffenwerkstatt at Dachau was finished, which was 1941. The picture below is of that work IMO, you can see the large number of guns in process in just this photo.
Let me restate something - the timeline for the update seems coincidental, but think about what was going on in the SS. In Feb. 1940, the directive appears in the Heeres Verordnungblatt allowing the SS-VT access to small arms from Army stores. Prior to this, the SS armed all of their own soldiers in the SS-VT with the SS Gew conversions. In 1940, the SS-VT was about 50,000 strong, so you guess how many SS Gew conversions they had on hand for the SS-VT (it had to have been a lot). When the SS-VT comes under the control of the Army for operations, they get new rifles from Army stores. It's my thought that at this time the SS Gew conversion rifles were returned to SS depots, namely the depot at Dachau. Is it possible that the Waffenwerkstatt at Dachau was specifically set up for this event? It seems like it's possible, just a thought. As the SS-VT converted to the Waffen-SS, surely they expected some increased force numbers and repair would have been needed. BUT - remember that the SS used Army dopots for repair work, I'd bet the majority of Waffen-SS weapons repair went to Army depots, but that is a guess. It's known that some normal, Army produced K98k rifles went through the SS2 depot (99% sure that is Dachau) as we have examples of them. Anyway, These returned rifles were then reworked into bent bolt/spring band setup.
My personal feeling is most of the SS Gew rifles were relegated to training units after that. The Army directive specifically excluded replacement units from receiving rifles, so it makes sense (at least to me) that the SS training units were probably the ones that got these bent bolt/band spring rifles. This also may explain why so many of the SS Gew rifles you find are so worn/mismatched? To me rifles used for training take more daily abuse than rifles in combat units. I'm attaching the Army directive, its on P.715 of Vol.2:
241. Dispensing of weapons, ammunition
and Heer equipment, basic material, operating
fluids and cleaning material during deployment
of the Wehrmacht.
For the duration of the special deployment of the Wehrmacht,
weapons, ammunition and Heer equipment, basic material,
operating fluids and cleaning material are to be handed over
to troops and departments of the Wehrmacht without cost
reimbursement, the material gets handed over against a note
document. The same directive applies to the following formations
which are subordinated to the Wehrmacht:
1. the SS-Verfügungstruppe,
2. the SS-Totenkopf-Division and
3. the Polizei-Division.
For the sake of clarity, it should be pointed out that these
formation do not reckon:
The replacement units of the formations mentioned under 1.
to 3., the SS-Totenkopf units, the Polizei-formations (SS-Polizei
reinforcements, reinforced police protection) as well as the other
division of the NSDAP.
Weapons, ammunition and equipment, etc., may be handed
over free of charge to the division of the Reichsarbeitsdienst (Reich
Labour Service) only for the duration of their deployment for the
Wehrmacht.
