What Seat is this For?

[Milan]

I got this great seat.
Thought is was for an RD350 F2.
But its not.

Anyone know what it fits?
No part # on it

Looks like an RZ 350 seat

Here's an RZ seat.

does not fit my RZ, nor the F2 model.
Maybe a 1981-82 seat?

Possibly an older Seca 550 or 650??

I was thinking XJ 550. The metal part holding the strap is wrong. Otherwise it looks like a pre-Seca XJ. After '84 they dropped the strap.

I was initially thinking 1981 Seca 550 since I parted 1 out 20 years ago and hung onto the seat. Having a look at this Yamaha parts diagram, it seems the rear upturn and brackets don't match the pictured example in this thread.
