Al, Once again a thanks is due.!
The lower barrel, I agree, has the BAR Model 30 look about it. I can't find anything with the gas mechanism that is the same. Having been bored and fitted in 7.62 x 39 clearly indicated a Chinese link sometime in its life... Clearly post WW2..
I'm not a 1918 BAR fan and have passed them down the line over the years. I have a FND only due to the flexibility of caliber with that configuration.
And yes, I have to have a one BAR in the collection...Is the barrel fixed on all BAR's including the Model 30 prior to the FND?
I've got piles of crated parts to ID in the next few months all the help here is appreciated.
