I have one of the Nickel Hi Power's from the last production run they did on them. They are Electroless Nickel. More bright than Satin. I bought it new in 1985. I have adjustible sights in Nickel with the gold plated trigger and checkered walnut grips with the Browning Medallion. Mine is flawless still. No flaking, no scratches, etc. Looks like Stepen Camp's pic except with adjustible sights. Mine also came with 2 13rd mags.
I have seen similar ones for auction at gunbroker.com for $1,250.
Considering I just saw a new BHP in Hard Chrome, fixed sights and rubber grips, for $700 "on sale", I guess the Nickel ones are easily worth $1,000 to a collector. If I had to take that $700 new gun and put wood grips and the old style Browning adjustible sights on it, I'd be looking at $950 to $1,000 easily.
Yeah blade 67, they may look like "pimp daddy" guns but that's because you're jealous and probably can't afford anything that cool! There's always a Shiney new Lorcin. Now there's a real "pimp daddy" gun!
