Interestingly marked MP5

[OnyxSkyDV]

So I recently picked up a MP5 parts gun to use for a build, and as I dug into it I noticed it was marked somewhat interestingly.


The bolt head is marked with a London proof mark, a crown with GP underneath. also with a date code of IS271. The bolt carrier is marked IS, and the same London proof mark is repeated on the front left of the receiver near the tack welds, inline with the rails. NP is marked over a B6 also next to the proof mark.

The barrel is marked with the London proof mark of the arm holding a sword, and NP (Nitroproof.), and a K504.

The left hand side of the mag well is marked Cal 9x19mm (not Kal) and the right hand side is blank.

The top is marked HK MP5, but of course the SN is cut off, so I can't get any leads on that.

Doing some research this may be one of the MP5's that HK build, but sent to Enfield/RSAF/BAE to assemble, though its hard to pinpoint the timeframe as I have a difficult time coming up with a date for that IS271 datecode.
(Maybe related to this? https://www.independent.co.uk/news/...apons-to-east-germany-arms-deals-1429337.html )

Thought it was interesting never the less and though you might too. Someone might even have some insight for me.

Current plans are sending it to visit Ralph next week for a beauty treatment.

Interesting kit--- IS = 1995--- these are the various date codes for 1993-2001 (different than the "usual" numbering system):

IR/ir-93; IE/ie-94; IS/is-95; IK/ik-96; IO/io-97; ID/id-98; II/ii-99; OR/or-00; NP/np-01

Thanks Tony, I think you are the only person I've seen who even lists those date codes. (Found them in one other post of your's previously).

Does anyone know what years BAE was potentially assembling MP5's? The lack of markings on the right side mag well makes me wonder if it was a deliberate omission of the origin of the firearm.

Cheers!

Well, its been a while in the making, but I got a chance to pick it up from Ralph, and I have to say it came out nice.



Just for fun I picked up some Cetme wood furniture, and a G3 rear stock. Removed the metal rear cap from the G3, and modified that to fit the back of the MP5. After a fair bit of hand finishing and some custom hardware to make it all fit, plus working on the front grip, I was able to refinish the wood for a retro look to the gun.



Was able to add a SD also, so now its a K, MP5-n, and SD.

I bought and sold a Brit 33K parts kit. I'm sure somebody with a welder could have fixed it.

Love the 33k kit, wish my own 33k had an original barrel. Looking forward to seeing it whole again.

Would have loved to get a hold of that!

An excellent trio--- I like the wood furniture.
