New Mystery Barreled Reciever need the experts

[sabinerat]

OK got our last shipment of barrel receivers in and this one was in the group need help IDing and date manufactured

Having a little trouble blowing up the pictures, only one I can really see clearly enough is #2 and appears to be a Chinese letter series gun.
1959-60 if I remember that correctly, so like a 50/50 chance.

but it has no Arsenal marking thought this may be a Ghost Gun

Triangle shape arsenal marking and Chinese characters 'Type 56' are in your 1st photo.

1st pic looks like a /606\ 25M receiver. 2nd pic SN looks like a letter gun, but without the arsenal stamp it could be a ghost gun. 3rd pic I can't make out.

25th year = 1980
N#### = 1950-60 letter gun from Jianshe
Third one is way too low resolution to distinguish anything.

Do you have larger photos? Maybe you chose the thumbnail size from imgbb, because they're only about 26-31kb

Definitely need better photos.  The second one may be missing a /26\ stamp.  That one could be an interesting gun!

Ok let me try this again didnt mean to put the 606 on last time also get some 666s

I very well could be crazy, but does anyone else see something right here? (might have to turn your head, having trouble rotating the image at the moment  )

[Boris Badinov]

OP-


The N letter action has a large collar barrel?

[Justin Hell]

Could it be a scrubbed and restamped letter gun?  Those edges look sharpened...could be where the /26\ stamp went.

Does look to be a faint stamp mark and definitely in the right location for it.

It’s there but I can’t make it out
2nd one I can’t see

That a 606 I accidently put on was using my phone
