Spurs for vintage bass drums

Spurs for vintage bass drums - if you have a old vintage bass drum that don't have spurs, and maby you don't want to drill the shell and mount the new type spures it mite devalue the vintage drum,i have a vintage leedy bass I use ludwig 6inch cow bell holders that clamp right on the front bass drum hoop, use a small rubber tip on the end if the holder is mounted in the right place thay hold very good, and look vintage.mount them so the front of the bass is 1 in. off the floor. - fred
