Heretofore in order to- make an inexpensive
ornamental cover for thelscal'e. members of they
knifexframe it has been the‘practice to provide
a decorative member which‘ was held to each scale‘
by a. mounting‘ member comprisingv a pair' of
metallicbolsters-‘joined by an intermediate me
tallic portion.
It is an object of the present invention to pro-»
vide a'construction for ornamental‘covering‘units
which, by' using; separate ‘bolsters, does‘ away‘
