I am not familiar with this particular model (427) but I am familiar with Benjamin air rifle. If your problem is that there is on Scope rail to mount your scope then I know how to fix it. Crosman airguns owns Benjamin air guns. Crosman offers a special Benjamin barrel clamp that lets you mount a scope to it. See the link below
You need to talk to a gunsmith.
This would be very difficult as the Springfield Model 15 .22 caliber rifle is already an antique. Try the Burris 3 - 9 x 40 scope and hopefully there will be enough room for the holes to mount.
There are numberous ones. The only limitation is your bank account.
Almost any air rifle scope will fit a Daisy. Check Walmart or a sporting goods store for a Daisy scope. But any air rifle scope should fit the dovetail mount that is on the rifle.
Best left to a good gunsmith.
In 1938, Remington began offering that scope on the Model 341 rifle. When you bought it WITH the rifle, it was $8.25.
I'd start with Amazon. Your rifle is a Savage model 340, and if you search for Savage 340 scope mount, you will get a lot of hits. The mount and a set of rings is about $53.98. Shoot safe and often.
