Wanted: MLM or MLE rear sling swivel

I have an 1898 dated MLE with an incorrect rear sling swivel, so I'm looking for a rear sling swivel for a Magazine Lee Metford or Magazine Lee Enfield (long lee) to bring the rifle back to its original configuration. Alternatively if you have a sporterized/damaged one of these rifles with this part on it and you don't want to part it out I'd consider buying a whole rifle.
