HD7 serial number

[khyron]

I am trying to find the serial number for an HD7.
The book says upper right side rear of the transmission. I am pretty sure i am not looking for a plate, but i can't seem to find stamped numbers that would match up to the SN breakdown either. It does have a bit of mud on it, but SN shouldn't be hidden, right?

Thanks

The serie number is stamp on rear right side back housing and maybe you need to scape the paint.
