The Beechcraft you are referring to as my "prize UC-45J" 029585 is actually an RC-45J photo recon Beech.
First of all, my bad. I had too many Web pages open while writing that and had "UC-45J" stuck in my head. And I said it was Taigh's "prize" airplane because he won a prize for it. Simple.

I think that it is perfectly legitimate to use the Navy Bureau number as a serial number for the registration of this aircraft. The Navy used it exclusively
Maybe in this case, but I know of many warbirds that were used by more than one branch of the service, each of which assigned its own "serial number." So which one do you use for a civilian registration; any one you want? That would result in chaos. Hmmm, and since it seems that that is exactly what we have here....
Cessna 310's served in the USAF as U-3A's and U-3B's, later as L-27's. Some of them were later transferred to Air Guard units, the Army, and even the Navy.
The aforementioned Grumman Albatrosses (an earlier post in this thread) were designed for the USN but actually first delivered to the USAF. Many of the early USAF SA-16A aircraft were later rebuilt as long-winged B or, if re-issued to the USCG, as E models (HU-16 after 1962....) The USAF serials were usually truncated for use by the Coast Guard. For example, SA-16A Grumman serial number G-100 was 51-026 in the USAF; it became 1026 in the USCG - and that is how it was registered as N7027T. But by your reasoning, it would have been OK to use 51-026; it had that serial number "first", that was what the USAF gave it and was presumably on the procurement contract to Grumman.
Serial numbers are supposed to be UNIQUE identifiers. They should not change with the owner/operator and the owner/operator should not have a choice to pick whichever prior military "serial" he wants to use. The true serial number should always be the unique, "internal" if you will, manufacturer's serial or construction number. That is how I have always interpreted the regs and it is also the clear intention of the darn AC that I am having trouble finding again - which as I noted before specially excludes the use of prior military serials - probably for just this reason.

Many ex military Twin Beech's were also registered with their civil model designations which, causes maintenance problems in my book. There are significant differences between a D-18 and a UC-45J but there are many military aircraft that have assumed the civil model designation. AD's come into play with the model differences and we have found many aircraft that have never had certain AD's complied with simply because they were registered as their civil counterpart.
Per Point 3, that is all true for Grumman G-21 series Gooses too. Even though the TC (654) recognizes all military model designations except the G-21B pure flying boats (no landing gear at all), it does not recognize the fact that the JRF-1's, -1A's, -2's, -3's, -4's, -5's, and the British JRF-6B versions were actually a mix Grumman models G-36, G-38, and G-39. The single JRF prototype was designated a XJ3F-1 by the USN and FAA, but it was a G-26 to Grumman. And the FAA does not distinguish between any of them; to the FAA, they are all just G-21A's even though there were significant differences in equipment. The JRF-1A's, -4's, and -5's all had big camera well hatches that could also be used for deploying a towed target for aerial gunnery practice - that makes a big difference in a seaplane.
As far as maintenance documentation for Gooses is concerned, it is all problematic. Grumman had a joke of a "Maintenance & Erection Handbook" for civilian owners and they put together a structural repair manual for the Navy - in spite of which most operators still use AC 43.13-1 for a repair reference. All of the "parts manuals" are really just "bills of material" or accounting price lists of spare parts (Those 1942 prices are to die for!) Nothing is illustrated and there are no exploded parts breakdowns. As for AD notes, the few that apply to the Goose series apply equally to all unless differentiated by Grumman serial number.

Yes there is a wide range of problems with the civil registry that has been going on since the registration began... I think the feds are aware of this and they are doing something about it. They are presently cleaning up the registry and bouncing out aircraft whose owners do not respond to the tri-annual inquiry cards. Many aircraft do not exist anymore...
Also quite true of Gooses. The first Goose intended to be used for the TV show Tales of the Gold Monkey, s/n B-112 registered as N2845D, crashed at sea and sank in the Gulf of Alaska on its way South - in 1982! It is one of many such Gooses still on the registry. Several Gooses that belonged to Antilles Air Boats are still also on the registry - in spite of the fact that Antilles Air Boats folded in 1988 after Hugo destroyed many of its aircraft. Dean Franklin obtained many of them and salvaged or scrapped them. How many "Undel Tri" notations do you have to get before the spurious registrations are purged?
