the spherical grip mounted on a circular rose,

This smart 19th Century design, was ubiquitous in Victorian housing stock. Here nickel-plated, this pattern can work beautifully in contemporary schemes. Suitable for internal mortise lock but not intended for rim locks (for rim locks one rose must be omitted but with this pattern the rose is integral). Spindle gauge is standard and should work in any English mortise or rim lock. These are reproduction door-knobs so can be ordered in quantity if required.
