Well, I'll be extremely interested to see those pictures. I checked Dr. Graham's book; the original release date of the original Revell Bounty was 1956; the kit number was H-327. It was reissued three times during the period covered by the book: in 1961 (with the kit number H-326 - yes, a lower number than the original), 1972 (as H-318), and 1978 (as H-338).
A couple of points need to be born in mind here. First - Dr. Graham's coverage stops in 1979. (I know for a fact that the kit has been released at least once since then in the U.S. - and probably more often than that.) Second - the book's coverage is restricted to Revell of the U.S.A. Manufacturing plants in other countries have issued kits under the Revell label that aren't covered by the book. (I know of at least three: Great Britain, Germany, and Brazil.)
I can think of one possible explanation for the origin of the smaller kit that Wojszwillo has. Quite a few years ago (in the mid-1960s, I think) Lindberg released a small series of sailing ship kits that duplicated Revell subjects on smaller scales. I haven't seen any of them in years, but I can remember buying a couple of them when they were new. It was obvious that Lindberg had copied the Revell ones with a pantograph machine (or something similar), eliminating some of the small parts but otherwise reproducing the Revell ones with great accuracy on smaller scales - right down to the little plastic coils of rope lying on the decks of some of them. I can remember three of them quite clearly: H.M.S. Victory, the clipper Flying Cloud, and H.M.S. Bounty. (I think there may have been a Santa Maria as well.)
Our good Forum friend from Belgium, Michelvrtg, has a website on which he describes all the H.M.S. Victory kits he's been able to find, including that Lindberg one: http://www.hmsvictoryscalemodels.be/LINDBERG_EN.htm .
Michel also illustrates two different Revell versions of the Victory (in six different boxes): http://www.hmsvictoryscalemodels.be/REVELL_EN.htm .
All but one of these are in fact reissues of the same kit (which appeared initially in the U.S. in 1959). The people responsible for marketing it apparently have never been able to figure out what scale it's on, but Michel figures it's about 1/220. (It's actually, for its size and age, an excellent kit; I'd probably rate it second behind the big Heller version in terms of accuracy.)
Then there's a smaller kit, of which Michel says: "The origin of this model is unknown (made by another manufacturer, reboxed by Revell.)"
I have a suspicion (it's no more than that; I haven't seen this mysterious little Revell kit, and I last saw the Lindberg one about forty years ago) that the "pirated" Lindberg kit (actually a shrunken, pantographed version of the old 1/220 Revell one) somehow, by means of the intricate relationships between kit manufacturers, made it into a Revell box in Europe. And now I'm wondering if the "pirated" Lindberg Bounty has done the same thing.
To my knowledge the only "Beagle" Revell has ever released - thank goodness - is the one that was based on the original, 1/110 Bounty. If I'm right about the smaller Bounty being the old Lindberg one, that would explain why Wojszwillo's "Beagle" is so much bigger.
And if Wojszwillo does have a Lindberg kit reissued in a Revell box, I suspect it is indeed a rare kit. I'm no expert in the kit collecting market, but it seems like it ought to be worth a fair amount of money.
As I said, I'll be very interested to see those pictures.
