As noted, F.78s are of reasonable quality, especially for 1944. This card is of no exception.
On the photo the serial FB353 is clearly visible, so given the aircraft still has markings of 316 and just a new squadron code, there is no doubt it is ex-SZ-H.

Well Franek

We are back to square one again.:)
The only photo I have seen of PK-H has an unreadable serial number.

Do you have another one?

As noted, I have been not researching that for a while, so while I have the photo, I have no idea where to look for it.
RAF Mustangs are being researched, so this information shall appear at some point. There is plenty of records, indeed, not just F.78s & F.541s.
