TBF/TBM Avengers in Japanese Markings?

I have an old book (I can't tell the actual title, as the book is in Japanese...my best guess is 50 Years of Japanese Aviation) that has a photo of two JMSDF Avengers in formation. One is a TBM-3S in what looks to be overall light gray with a black anti-glare panel ahead of the cockpit. The other is a TBM-3W in overall glossy sea blue. Both aircraft have oversized 3-digit buzz codes on the cowlings, and 4-digit serials on the tail, prefixed with the katakana symbol "Ka" (for Kai, "Sea") and a hyphen. There are also the usual Japanese kanji JMSDF slogans on the rear fuselages and white-edged hinomaru on the fuselages and wing positions. The -3W aircraft's markings are included as a choice from the High Planes 1/72nd scale conversion kit.

According to warbirdregistry.org, there are three preserved JMSDF Avengers, but they don't have photos of any of them in their database. Stephen Bierce

I have a few good photos, drawings in the MAI files.

Drop me a line and I'll see what I can do.

I thought "Kai" meant "modified".
