No last round device, only the bolt handle that can be used to lock the bolt back.
Scope mounting on the classic requires a scope rail, they came with the gun, but many used guns won't have them. The factory will send you one for free, if you call them, or you can buy aftermarket models on Ebay.
The factory one is a short non-standard rail, most Weavers will work, Pic stuff won't. You remove the receiver cover, take off the irons, and mount the rail in their place, and put the cover back on the gun. It is short, but functional.
You can sorta almost see it in this picture.
