Erfurt c/RC mark survey

Dwight Gruber · 06-12-2006, 03:16 PM

Updated 11/07/06
Most current version of the database
The Ph entries are from photographs, not all pistol views were shown and so there could be marks missing from these rerports.

----------------------------------------------------------------------------------

A very interesting and informative discussion about the WWI Revisions-Commission and c/RC markings on Erfurt Lugers () has reminded me of the brief attempt a year or so ago here on this Forum to survey the predominance of c/RC markings, by year, on Erfurt Lugers. The discussion has got my data juices flowing, so I am resurrecting the survey in hopes of doing a proper datbase.

There have been an number of good responses, and I have mined the Forums for data (there are a surprising number of good reports). The database is complex enough that it is easiest to snapshot the spreadsheet and present it here (current as of 6/15):

You can see the kind of data I am looking for:

Year
Serial number
standard or LP (1914)

c/RC marks on:
Barrel-above inspector mark
Barrel-elsewhere

Reciever-above hardness mark
Receiver-sear bar
Receiver-elsewhere

Toggle train-breechblock
Toggle train-center toggle
Toggle train-rear toggle
Toggle train-elsewhere

Frame-trigger guard
Frame-left frame rail
Frame-elsewhere

Trigger plate-exterior
Trigger plate-trigger lever

Takedown lever

Anywhere else not specified

Since there were a number of DWM c/RC marks reported I am including them and looking for more.

Thanks very much to everyone who has responded so far. If anyone else has information to add, please post the information here or email me [email protected] . I will continue to update the database post every so often.

Dwight...soryy I missed this post. Here's the info on mine...

1916 Erfurt sn 2947n (standard)
c/RC right side receiver over inspection marks
c/RC front top of trigger guard

1918 Erfurt sn 5830d (standard)
c/RC right side receiver over inspection marks
c/RC over sn on rear flat side of rear toggle piece
c/RC front top of trigger guard
c/RC right side of breechblock (mark is exposed when gun assembled)

Looks like the 1918's were pieced together for production from whatever they could get their hands on as quickly as possible. Hope this helps.....Cheers....G

I have posted the current database in a revised first post to this discussion. My thanks to everyone who has provided data so far.

Dwight,
Can you post a picture of the mark we are looking for. My 1917 Erfurt does not appear to have a c/RC (assuming that means a crown over the initials RC) on it, but I would like to know what the mark looks like.

Ron, and Karl.

Thanks very much for the info.

William,

Here is a shot of the c/RC mark, its the best one I have and not very good at that, but it should get the point across.

thorin6 · 06-15-2006, 11:05 PM

Year 1917
SN 9358d
Standard
c/RC above proof marks on right front of receiver

Ron Wood · 06-15-2006, 11:29 PM

Dwight,

1912
#719a
Standard
C/RC Trigger Guard (tucked way up in the curve where the guard meets the frame in front...almost missed it)

I know it sounds a little cynical, but I suspect that the C/RC marks show up with increasing frequency as the war progressed largely due to bureaucracy. The inspectors needed to justify their existence and keep their jobs.

Dwight Gruber · 06-16-2006, 04:12 AM

Karl, and Ron,

Thanks much for the info.

I'm not sure that that reason is cynical, but do we know if there was that kind of jeopardy?

--Dwight

Dwight Gruber · 06-16-2006, 07:17 AM

There have been quite few posts and emails of c/RC details, and I have mined Imperial Lugers and Weimar Lugers for c/RC marks. This has more than doubled the data, so I have edited the top post to include the current spreadsheet. The photo notation indicates that all views were not always available for examination.

Continued thanks to everyone who has participated.

--Dwight

thorin6 · 06-17-2006, 05:23 PM

Dwight,
In your spreadsheet you note that my SN has 2 marks (1917 SN 9358d), but I only saw the one on the receiver--there isn't any mark on the trigger guard.

William,

A transcription error, thanks very much for pointing it out (and for the info, as well). Fixed on my database, it will show up next time I update the post.

Thanks again to everybody who has responded.

micmacman · 11-19-2006, 08:31 PM

i just put a Erfurt Luger on layaway,a 1917 that has the C/RC marking on it as well

i have a couple Gew 88 Commission rifles that have the same proof,and a while back we had a discussion about it when i inquired about what its distinction was,and all that chimed in had it on a Erfurt Gew 88

is this a proof mark indicative to the Erfurt arsenal solely?

also what was determined the meaning of the mark (not 100% sure if correct) was that it signified a part that had a correctable flaw,that merely need some minor attention to bring up to standard,,,,,is this correct?

also what do you mean by "standard or LP"?

year -1917

serial#- 7661f

reciver right side above inspection proofs
forward part of trigger guard

i will examine more closely when i get it paid off and edit as needed

reich1900 · 11-19-2006, 08:42 PM

Hi Dwight, I didn't see my 1918 Erfurt ser# 6520q , that I posted earlier, on your updated list. Is it an over sight?
