Dogtrk, as stated many times before, the market value will be what one is willing to pay at any given moment. The market is very soft in general, but for rarer pieces like yours, it will more than likely show itself to be easily sold, at the appropriate price. For those with the skills to fabricate or source the rest of the gun, they may pay $2400 for the parts you have. Having a FULLY BUILT Owen is something to behold. In general, I would think about $600 for the barrel and $600 for the stock assembly as individual parts. That is somewhat high for my tatses, but I know people will spend money on rare material. Magazines would probably be between $50 to $95 a piece, so a $450 minimum for mags. These numbers are based on many years of purchasing off of GB and other mainly Title 1 populated web sites. I am not a regular machine gun attendee, like Knob Creek. True machine gun stuff probably sell at higher prices, because the guns sell for higher prices. But we know the "parts" of many items sell for quite cheap at times. I base this on what similar products run (Sterling L2A1 Sub Gun, Lancaster parts sets, etc.) Unless there are a good number of FA weapons in the US, which I have NO clue? But without any additional parts or means of securing them (which is getting more and more difficult), it is a $1650 ticket to nowhere. Apologies if that sounds harsh. I am sure many will dispute my evaluation. Just one man's opinion. Heck, some guys are just happy to have parts to such things.
