Ah. 'Cept for one thing: Birddog13's specimen is MUCH higher quality than the one Bluesbear pictured.
OK, go to the high-res version of BD13's gun. Look at the trigger guard - look at the bases where the triggerguard "ring" hits the part that screws to the frame. Look at how clean AND complex the grids are right there. I'm serious - those junctions on the BD13 gun appear to be done by hand. Now look at the BD13 trigger - it's of varying thicknesses, unlike the one Bluesbear posted. Reminds me of a fine shotgun trigger.
I could go on...the grip shape, hammer shape, many other details are similarly "highly tuned" or whatever you want to call it on the BD13 piece.
It might indeed be a clone...but if so, it was made by somebody who really, REALLY gave a damn about quality.
