Dual 1581 on ebay, I just emailed asking Tranny numbers

[siggy14]

Just curious if it has the pre 500 or not, so i figured I would ask him. Not a bad BIN.

This was the response, not both, just gave me one.

Dear zerodc,

Sure - they say:
Mesa

E1A606-228

Hope this helps! Any other questions let me know. Thanks!

Out of curiosity, what do those numbers tell you about that head?
