Aquarian Modern Vintage Medium Texture Coated 16" Drum Head MOTC-M16 (new) Brand_Andante At least I think this

At least I think this is pre international its super tight  but will just about fit over a regular 22" shell

Some rust spots

wider angle (θ) between the force of stepping on the footboard (F1) and the force of pulling the chain from the sprocket (F2) makes less power of F1 if the same F2 power is required

in contrast to the Alpine Pluggies Kids which contains a hard filter

The plastic part and the rolling spacer are the same as on some iron cobras- not the screw)
