All four of these are recent Model 1s.
Top to bottom:
1-7 AG Russell golden maple burl handle with black and brass spacers
1-8 stag with lugged brass hilt and brass and red spacers and brass butt with thong hole
1-6 yellow micarta finger grips with NS hilt, aluminum and black spacers, alum. butt with thong hole
1-7 pure stock except that it has been refinished by the shop
The colors are not very accurate in this PIC. The yellow micarta is not nearly as orange as it looks in the PIC.
