Interesting, I'd read about this one in 2nd Tactical Air Force Vol.4, this aircraft had appeared in print before but the letter code to match the serial MP147 had been unknown (erroneously thought to be either '?' or 'A' or 'Z') due to a lack of substantiating photos. Looks like they finally found some... 'U'.
As time goes by unfortunately more information on aircraft that have been a mystery as to what they looked like are slowly coming to light. As the servicemen are dieing off their belongings such as photos are being sold off or donated by family members to museums.
For example this picture I found just tacked on the wall at a private Museum I visited in Australia over Christmas.

For years I have been looking for a complete photo of this plane in it's bare metal livery but could only find partial pictures of it as I was researching it for possible inclusion in AHII. I am still looking for a piece of missing info I once had & I think it may be eligible?
Any ways back to my point it belonged to a former RAAF member who died & a relative just walked in to the museum & just handed it to them.
So in one way a boon for the likes of us & historians & sadly a reminder of a generation that is fading away.
