[COLOR="DarkRed"]It's a middlin' price for the Slingys because: there's no snare drum (I know exactly the kit you speak of, it came equipped with a COS snare drum originally)...the color is very typical...and they are concert toms.
If seller is open to an offer, I'd offer $375 ....assuming all of the original tom mount, bass spurs, and FT leg mount hardware is intact and operable. If he drives a hard bargain....$400 wouldn't be out of the question if they ARE really in fine shape. You can always pick up a decent metal Slingy snare on eFlay for well under $100, to round out the kit....
Question then would be, are you cool with a concert tom setup ? They are out of vogue, have been for a while. Some folks don't dig the sound of 'em anymore...
But [COLOR="Red"]Devil's Advocate[/COLOR] would say that, again if the kit is in fine shape...there aren't a whole lotta those '70's Slingy concert tom kits which are in fine shape any longer....so.....[/COLOR]
[COLOR="Purple"]The Royces...need more info...condition, finish (gloss black, black sparkle, black pearl ?), what do the badges look like ? How many pcs ?
Royce was a typical 60's Japanese stencil, so that vintage is as good as any other '60's stencil....but in the '70's they got really, really janky.[/COLOR]
