I'm a sucker for Minimags with splash parts! Your Eclipse body rail, sight rail, foregrip & powerfeed plug scream oldschool-cool. Definately keepers.
From an aesthetic point of view I would do a few low cost things:
-I would buy a dust silver or chrome asa, a CP on/off preferably, to blend with everything else.
-Polish the Minimag body. You can do this yourself with 400, 600, & 1200 grade sandpaper from Ace hardware, and some Mothers Mag polish. Theres many how-to threads on the forum. Nothing beats a polished Minimag body, however it will collect fingerprints like you read about!
-Buy either a chrome intelli double finger triggerframe, or a chrome Benchmark single triggerframe for more of an old school look. Some fields may be iffy about you playing with a cut-off trigger guard. With .45 based frames, you have almost endless options for custom grip panels.
-Sell, or trade, your Hurricane valve for whatever you can get, and buy either a used numbers matching Minimag Valve, a Retro Valve, or an X-valve. Try to get one that already has a Lvl-10 bolt. All of these can be had here on the buyers forums for relatively cheap nowadays.
Congrats, that was an excellent Minimag catch!
