[Dx-qsl] QSL-Info XF4MF from 1997

[SM5DJZ Jan/John]

Hello.

When looking through my old logbook, I found a QSO with XF4MF on July 12th 1997 on 40 meters - CW.
Unfortunately I haven't received any QSL and now wonder if anyone out there can provide any info to confirm
that this is a contact with Revilla Gigedo, or is it the mainland Mexico. Clublog say Rev. Gigedo.

Any QSL-info for this call would be very much appreciated whever I can obtain a written confirmation.

Thanks for all help
