Sd.Kfz.173,
The only thing that I saw on "BRP"s web-page was the front-half of an original MG34 Blank-Barrel-Assembly......they do not have the missing rear-section.
....unless you saw it someplace that I did not (?).

Panzercanuck,
The best way to Blank-Adapt the SA34 (MG34) is with a 2-pcs. Blank-Barrel-Assembly. It requires less pressure to operate and that allows it to make more noise out the front and be adaptable to fire both 8x57mm Blanks and the cheaper 7.62x51mm/.308 cal. surplus Blanks on the market.
With that said.....I make and sell these 2-pcs. Blank-Barrel-Assemblies as fitted sets:
1: Just 8x57mm 2-pcs. Blank-Barrel-Assembly.
2: Just 7.62x51mm/.308 cal 2-pcs. Blank-Barrel-Assembly.
3: A fitted set with both calibers (8x57mm and 7.62x51mm/.308 cal.).
These come with additional allen-set-screw for the front-restriction.
I also sell the much needed "L"-shapped" feed-tray-spacer that you need for reliable feeding of shorter Blanks.......(NOTE: Full-Length 8x57mm Blanks are currently selling for about $60 per 100 plus shipping).
I can help guide you through the Blank-Adapting-process.........you will need about 20-50 Blanks for set-up......"but" with a "TNW" SA34, you really need to:
1: Read up on these in our MG34-Sections and pay particular attention to the "Blank-Adapting the MG34/SA34 Section".
2: Polish the guns inner working-surfaces for better operation.
3: You will need to insure that the SA34 that you buy will funtion with live ammo fired by you (not "TNW"s word)...and that the weapon fires without feeding issues.
4: The you will need to select a Blank-Adapting "system" that you will use. Again, the 2-pcs. Blank-Barrel-Assembly is the best way to go and more readily adaptable to a different Blanks...especially the 7.62x51mm/.308 surplus Blanks on the market.
5: TNW builds their SA34s themselves.....and as such, each one is very-different.....and a challange on their own to get to operate reliably with live ammo.
With that said, your gun may require either a longer "trigger-sear" (sold by one of our Board-Members), and/or spacing of the 2-pcs. Blank-Barrel-Assembly due to TNW's sear length/location. I can also help you with this.
(NOTE: We have several MG34s and several SA34s running well with these 2-pcs. Blank-Barrel-Assemblies....and I have a limited supply of these being machined this week.).
I have provided photos of the 2-pcs. Blank-Barrels-Assemblies that we are making for the MG34/SA34 and the MG42/SA42 below.
Last.....please direct any Blank-related questions on the MG34/SA34 to the "Blank-Adapting the MG34/SA34" Section. This will help more reenactors with information in one area.
The MG42/SA42 has its own Blank-Adapting Section under the MG42-Section.
