Gevarm 22's

[Doc.Holliday]

I am asking if Anyone can tell me if a Gevarm A7 semi auto 22 has a checkered or plain stock?
I have seen pictures of checkered stocked Gevarms called a model A7; and other pictures where the A3 has a checkered stock.
Yet the A7 was supposed to be the deluxe model.
I am thinking of buying one in very good condition with a plain full wood stock and a target front sight with inserts.
The seller can't seem to tell me the model ; so I am hoping the type of stock is an indicator for those in the know.
As well is the A7 is the only Gevarm which is of closed bolt design?

Thank-you
Doc.
