In an effort to solve this question, I requested a number of microfilm rolls from the Air Force Historical Research Agency related to the history of Davis-Monthan in 1946-1949. (Interestingly, in at least one of these cases I was the first one to do so, as they had to undergo a declassification review prior to being released, which is kind of cool.) The good news is that one of the reels,
B2152, had a page with a complete listing of the models - although not the serial numbers - stored:

During the three months covered by the above report, it took 11,182.5 labor hours, $12,045.68 in labor cost and $341.21 in material cost to maintain the 28 aircraft in storage. (For reference, according to an
inflation calculator this is approximately equivalent to $172,742.17 in labor cost and $4,893.15 in material cost in November 2024.) However, it is important to note that these costs varied widely. For example, from April to June 1948, it only took 440.0 labor hours, $572.44 in labor cost and $0.00 in material cost to maintain the same aircraft.
However, an excerpt from an earlier report notes 2 B-29s were dropped from the collection before the above:
Quote:
During the month of January 1947 one each TB-29 Nos. 45-21728 and 42-6364 were dropped from the Museum Storage Project and picked up on B-29 Storage Project STO 517.
(Source: "History of 4105th AAF Base Unit (Aircraft Storage) Davis-Monthan Field for 1 January - 31 March 1947," 1947, 7.)
The roll also contains details on the 1 August 1947 Air Force Day activities mentioned in a
previous post. If I have time, I may include it in a follow-up post, as it is quite interesting.
It is important to note that the 4105th AAF Base Unit (Aircraft Storage) was redesignated the 3040th Aircraft Storage Depot on 28 August 1948.
A second roll,
K2218, includes a few more bits of information. The report from 1946 to 1950 includes the following in the section for 1949:

Transfer of Museum Aircraft
One C-45 aircraft was transferred to the University of Minnesota,
Minneapolis, Minnesota. No Project Number was available. The transfer
was accomplished by ground transportation.
Museum Aircraft B-29, Serial No. 44-86292
This B-29, commonly known as the "Enola Gay", was processed for
transfer to the Air National Museum, Project A-201-SA.
[Ed. Unrelated entry omitted]
AT-7 Aircraft, Serial Number 41-1144
The aircraft was formerly designated as a museum aircraft, but
after transfer to regular storage, it was prepared for one-time flight,
Project ADC9ST-8, to the Pacific Overseas Airline Corporation, Ontario,
Canada. Contract AF33(038)5089. The aircraft departed 21 July.
[Ed. Unrelated entry omitted]
Reclamation
During the first quarter of 1949, reclamation was completed on
thirty-nine of the forty-three B-29 aircraft so designated. Reclama-
tion operations on fourteen museum aircraft were delayed because of
higher priority projects. During December one B-25 aircraft, serial
number 45-8813 was reclaimed in accordance with Air Force Regulation
65-86. One XCG-15 Glider was removed from storage and salvaged on
13 December 1949.

Joe Baugher's list, the University of Minnesota acquired one other aircraft that, whatever the fate of the C-45, survives to the present day: the RB-17E, 41-9210, now with the Wartime History Museum. However, this cannot be the RB-17E mentioned in the museum collection as 41-9210 was in use by Minneapolis-Honeywell from at least November 1944 until it was acquired by the school one year later.
By the end of 1950, only "four miscellaneous museum aircraft" were noted to remain. (Jontig, 31)
A further aircraft was disposed of in fall 1950 on the orders of the San Antonio Air Materiel Area:

Interestingly, it seems that even after the museum aircraft departed or were scrapped, one legacy remained. Shortly before the 3040th was reassigned to Norton Air Force Base on 1 June 1951, a unit called "Detachment #1, USAF Exhibit Unit" began taking travelling exhibits to various groups in the area. For their first outing, the unit took an XF-85, B-45 nose section, and J33 and R3350 cutaway engines to an event held by the Palm Springs Junior Chamber of Commerce in Palm Springs, California on 21 January 1951. A subsequent event on 2 February 1951 at Building T-670 for the Flying Safety Office at Norton Air Force Base included a
C-82 landing track. (Jontig, n.p.) So, it seems one can draw a line from the wartime
Air Cavalcade and Shot from the Sky exhibitions through the Davis-Monthan collection and the 1947 Air Force Day to the USAF Exhibit Unit. It seems quite possible that these exhibitions and subsequent disposals were what inspired a young high school senior named Ed Maloney to
buy a J8M1 Shusui in 1948. (He has certainly cited Arnold's drive to "
save one of everything" as a motivation.)
EDIT (25-02-03): Upon further review, it appears that the B-25J, 45-8813,
was indeed one of the museum aircraft. The confusion arises because of the following sentence:
Joseph J. Jontig wrote:
OPERATIONAL ACTIVITIES
Storage of Aircraft
At the end of the first quarter, the following aircraft were in
storage: five hundred thirty - five B-29 aircraft, one hundred forty-
one C-47 aircraft, one B-25 aircraft, one AT-7 and twenty-seven museum
aircraft.
(Source: Joseph J. Jontig, "History of the 3040th Aircraft Storage Squadron Davis-Monthan Air Force Base Tucson, Arizona: Historical Outline, Section I, 1 April 1946 - 31 December 1950; Semi-Annual History, Section II, 1 January 1951 - 30 June 1951," n.d., 24.)
At first glance, the fact that it is listed separately from the museum aircraft makes it appear that it was never part of the collection. However, what was likely the case is that it was dropped from the collection and transferred to regular storage pending future disposal as was done with the AT-7. Therefore, at the time of the report, it was formally no longer part of the collection. The following paragraph makes it clear by contrast how much the collection would be diminished by 1950:

At the close of the year, four hundred twenty-eight B-29 cocooned
aircraft, one hundred five B-29 non-cocooned aircraft, eighty-four C-47
