Spring-

First things first, you need to adjust the size of the image you have linked here.
The size you have in your post makes it very cumbersome to navigate this thread, anyone who's viewing this needs to pan the image side to side in order to see the gun and to read the messages.

Please edit this right away.

Now, on the gun...

The AYA No2 is a rather high quality piece, an example of some of the best work you'll see out of Eibar in a production gun.
This one appears to be in very good shape, and wonder if it's one of the 'rounded sidelock' models.
When you edit the photo size, also include images of the top of the gun, from the fences back over the wrist.
These guns are built to last a lifetime given they're maintained properly.
What did you pay for it?
