Nice of that rack seller to include the photo of mine in his ad! From the date, looks like it was shot at this year's Ripon show.
FYI - I no longer own any spare shotgun racks. The last one I had was a complete example for a Rangr equipped Mustang and it recently went for an in-progress '89 restoration out my way (and not for anything close to that eBay price!). I have photos of some of the pieces from it here:
