Hi, and welcome to the forum.
Do you mean the external Bracket on the right hull side?
I Dont know the answer to your question, but I suspect not. I think the external bracket was only fitted to early carriers, and I think the Flame thower carriers came along later.
I read somewhere lately that all the carriers after a certain production point were factory finished, With the holes, to be able to be fitted with a F.T.kit.
