Exactly why I had one once.........for about a week.......I personally like the look of some of the earlier USA ones, understand one at least of the (tenuous) advantages mooted about using indoors, but just cannot get my head around why anyone would bother with all the fiddle faddle and nasty plastic and roll pins (on ones I have been asked to repair at least).
Each to their own.......Mine is steel and walnut, quick pull on a barrel / lever....job done
