HK steel grip TSR markings info needed

[MSAA]

I’m looking for a Hk grip frame with 0 1 markings so I can insert my PSG1 trigger group and PSG1 wood grip and use it periodically on my HK91.

I want it to look “stock” so to say.

From what I can tell the PSG1 guns had 0 1 marked frames only, is this true?

Also I have come across one marked TSR

I’ve never seen those letters, what does it mean

any info is appreciated

HK91's had 3 different trigger pack housings, depending upon the manufacturing date:

1. "SF" (1974-1980);

2. "0-1" ("0 to the left of the "1")(1980-1988);

3. "0-1" ("0 to the right of the "1")(1988-1989).

The PSG1's have these trigger pack housings ("0 to the right of the "1").

CETME Modelo B and C:

- “TSR” lower (T- Tiro a Tiro- “shot by shot”/semi-automatic; S- Seguro- “secure”/safe; R- Rafagas- “bursts”/full automatic)

Thank you Tony!  Buddy said you would know 

since I’m somewhat of a noob, is this what you mean by the 0 to the left of the 1?

You're welcome.

Yes--- your picture is the "0" left of the "1" trigger pack housing.

Since I cannot seem to attach a picture, here is an auction with the "0" right of the "1" trigger pack housing:

Great so even thought my HK91 is IA 1980 SF marked 

to be “ period correct” for PSG1 I should get the 0 to the right of 1.  I’m assuming because the PSG1 came after 88?
