Any help Telling me what Donuts I have?

[wayfastwhitey]

So I bought these donuts second hand and have no idea what I have now.

They were all bagged in bunches:
-the two bunches ont the left have a fishy smell but the bottom look shrunken down like they may have been treated?
- The bunch in the center actually had Mossetti written on the bag and I believe they are older Mossetti donuts.
- The bottom right had Alpha on the bag and I guess thats what they are, seem to be the right hardness.

Any ideas on what the 2 bunches on the left are? Or the top right? I believe they are all still soft and usable and some measure between treated and soft wonder hardness.

I look forward to mounting them and seeing what they do

The Clark brothers, Garry and Steve, sourced some gray rubber that was amazing. It hardly wore, worked nearly as well as wonder and never seemed to dry out.
