Hi David,
If you haven't already seen it, there was an In Memorium posted with some lovely comments from members who knew your dad (sadly I never made his acquaintance).
Take care of falling foul of the Marketplace rules on here - they have been put in place mainly to stop scammers, and to help fund the site. I'm tagging @Rich who is one of the moderators who can hopefully advise you before posting anything that will breach these rules.
Sorry for your loss, and best wishes for the task in hand.
