here's a link to a bunch more pics as well:

I'd have to take the gun part again to make sure, but I'm pretty sure the bottom of the barrel on mine was marked with a 75, which matches the last two on the serial number. If it was rebarreled, it looks like it was done at the same time it was reblued/re-arsenaled.
