I think you will be very happy with the slip on pad. I actually like the looks of them. I did not picture it above, but I also have a lace-up pad that I think looks pretty neat on an old gun. At some point you have to "live and let live" with these old guns.
Now, the next inexpensive item that you might really like (I do) for your vintage SxS is a leather hand guard. I just like the look and feel of them. I rarely shoot at a rate that would really heat up the barrels at sporting, but if you shoot trap, they are very useful if you have a splinter forearm. I don't think your Eagle has a beavertail from the above post. Jeff's Outfitters carries them at a very good price. Jeff is a very nice guy and he has a lot of other gun cases and cleaning items. His website is nice and you might just enjoy looking at what he has.
