Looks like Peter's Tarka is back up for sale, via Collecting Cars auction:

https://collectingcars.com/for-sale/2014-morgan-plus-8-1

The summary notes an equestrian incident:

"Specific notes from the seller include: The nearside wings have been replaced and repainted by Morgan Motor Works due to a stationary incident where a horse walking over the car necessitated replacement."

I know Peter had some issues but that seems to be a new one!
