Ah, but there is the (possibility...) that the named horns play just that little bit better than the stencils, and/or are made with just that little bit more care and attention than the stencils,or is it all in the mind ?  The stencils are often made with 'last model' tooling, and don't have a great cash value, whereas 'name horns' can be an investment - look at Selmer MkVI's !

But players (like me) are quite happy to get great stencil horns at bargain prices, and can smile inwardly !  E.G. I've got a Conn stencil straight Soprano which is identical to a slightly earlier 'named' Conn Soprano (I've compared them side by side) - the only difference is that Conn stencils normally don't have the rolled toneholes, big deal !

So, stencils are (often) very good, and cheap, 'playing' horns.  But lower cash value.  If you want to pay (often more than) double the price, you can get a 'name' horn, which will hold - or even increase - its value.

But then again, as there are good and bad horns in any given range, you might get a great stencil that plays better than an indifferent 'name' horn.  The arguments can go on and on....   Hmmm, having written all this, I may turn it into a blog topic !  Nice to talk to you.  Alan
