Hi Brian:
I've got a note here, citing assorted squadron doccos, which says Sid Seid and Dave McIntosh were in HR149, TH-R on 21/22 June. I'll see what I can find for 6/7 July.
Incidentally, there is a photo at the Imperial War Museum collection - Photo No.: CH 20880 - which shows HX811 TH-K with all its paint scorched off, however it is not clear what date this latter incident was. A small scan of this pic is available here:

Type CH 20880 into the "Photograph Number" search box. On the left-hand side of the page which results, you'll see a hyperlink named
4700-16 - click on this and it should take you to a another window. Click on *that* image and you'll get a slightly larger view.
Cheers,
Mark
