That will require some production innovation, or they'll die off.
I agree with this observation up to a point... But:
Colt's current tooling situation is much better then it was at times in the past. Obsolete tooling isn't a major concern at this time.
It is unlikely that Colt could come up with many (if any) production innovations that they're major competitors don't already have and use.
You're clearly not getting this... If a deal could be crafted today amongst everyone who owns or is owed money by Colt to sell its assets for a price that could largely be serviced by its current operating income (which would require a deep discount for all), the assets would sell very, very quickly.
Once it was a going concern again it could easily be flipped for a premium.
Oh I get it just fine. I worked in various capacities within the firearms industry for over a half-century, and personally knew some of the principals in this story. Among other things I did extensive market studies for various parties.
At the present time Colt has 3 product lines to offer: AR15 rifles, 1911 style pistols, and 1873 Single Action Army "cowboy" revolvers. All these are literally filled with competitors making similar products, with many out producing Colt at what should be their own game.
While at the same time they have absolutely nothing in areas such as polymer constructed/striker fired/high magazine capacity magazine pistols of various sizes.
Now I personally have no fondness for these, but the truth is that they sell in far greater quantity then anything Colt has to offer, at a much lower production cost on one side, and profit return on the retail side. They also dominate most of the law enforcement market, which is a substantial component within total handgun sales.
And while I dearly love hand-ejector revolvers, I clearly understand that with the exception of small-frame snubbies the overall revolver market is declining, with every indications this trend will continue.
So any serious future investor in the Colt operation will before they jump, take a careful look at the handgun market as it exists in 2015 and probable future, and what they can expect to get from Colt's current assets - with a careful assessment of how they fit current (not past) market conditions. And after doing so will likely become disinterested - unless they can be added to a successful ongoing and established business that wants to plug some holes.
