Here is an original condition Meyer 4MS NYUSA alto mouthpiece. This piece measures .068" on my gauge.
The Meyer's from the 1960's are the quintessential alto mouthpieces and need no introduction. These are the designs that all modern 'jazz' mouthpieces are compared to. This is a rare find in that it is in near pristine original shape and features the desirable small chamber configuration. Focused and easy to control, the small chamber is very suited to classic jazz as well as more contemporary styles.
