Davidson's seems to have been the importer on a lot of these roughly machined guns...that 0226 project of mine was from Davidson's. It exhibits many of the same DB/DP attributes, I just wish I had more of the original parts to compare.
First real project SKS in Projects - Page 1 of 2Another thing I have been considering, since many of these seem to have fairly consistent lackluster machining, Made with a variety of lower grade components.... Could it be that 0226 made them all, and these city stamps could just be identifiers for police/security forces/militias in these particular locations? Later Security Forces guns were specifically marked for their purpose, possibly it was just done differently earlier on...and at a far less stringent factory with regard to quality control.
If this were the case, that further throws the meaning of DB/DP into question. I don't get the use of Roman lettering while at the same time still using Chinese. (usually) The 'Destination (insert nation here)' thing doesn't sit well with me. Why would an English abbreviation be stamped before Chinese characters? Lets also consider it very unlikely that anyone in Pakistan would be speaking English, and although English is a secondary language in Bangladesh...since one doesn't make sense at all, it seems likely that the other wouldn't be consistent with that train of thought either.
It seems more likely that it was either another instance of a factory using more than one code for the same location, or two factories using four different codes. If they were indeed foreign aid guns, why didn't they go there? Why would so many different factories be utilized for such a purpose?
Let it be known that I am grasping at straws here, and these ideas are pure speculation, lest we end up with more widespread wrong information...I bet Destination Bangladesh and Destination Pakistan was someones wild guess, and the internet just ran with it....and look at us now.
