I am looking to make or by a pre-selector for my S38 receiver.

Anyone have one or any ideas?

Decades ago, there was an article in CQ about improving a low end
receiver, I think it was the S38. They improved image rejection by
adding an untuned amplifier ahead of the receiver. It didn't add much
gain, but it isolated the first tuned circuit from the antenna, which
improved it's selectivity and hence the receiver's ability to reject
images. Kind of neat, though I have no idea how well it worked.
