`hg strip` normally keeps a backup inside the repo, to be restored with
`hg unbundle` (there's a setting to disable it, though, if I remember
correctly).

Do you have it ?

Here's an example:

    /tmp/teststrip $ hg log
    changeset:   1:654eabbbc66a
    tag:         tip
    user:        Georges Racinet <georges.racinet at octobus.net>
    date:        Wed Jul 21 12:30:33 2021 +0200
    summary:     foo2

    changeset:   0:ef0b809416af
    user:        Georges Racinet <georges.racinet at octobus.net>
    date:        Wed Jul 21 12:30:28 2021 +0200
    summary:     foo

    /tmp/teststrip $ hg strip -r 654eabbbc66a
    saved backup bundle to
    /tmp/teststrip/.hg/strip-backup/654eabbbc66a-caa0b8b0-backup.hg
    /tmp/teststrip $ hg log -r 654eabbbc66a
    abort: unknown revision '654eabbbc66a'  # yes it's been stripped

Now restoring (I suggest you make a full copy of the entire repo,
including those backups, before anything else).

    /tmp/teststrip $ hg unbundle
    /tmp/teststrip/.hg/strip-backup/654eabbbc66a-caa0b8b0-backup.hg

    adding changesets
    adding manifests
    adding file changes
    added 1 changesets with 1 changes to 1 files
    new changesets 654eabbbc66a (1 drafts)
    (run 'hg update' to get a working copy)
    /tmp/teststrip $ hg log -r 654eabbbc66a
    changeset:   1:654eabbbc66a
    tag:         tip
    user:        Georges Racinet <georges.racinet at octobus.net>
    date:        Wed Jul 21 12:30:33 2021 +0200
    summary:     foo2
