   Finding

   shipscribe (Stephen S. Roberts compilation of official Navy register/BuShips data) records ATR-37 ordered under contract of 1942-07-06, built by Lynch Ship Building at San Diego CA; keel laid 1942-09-30; launched 1944-01-26; commissioned 1944-09-20; decommissioned 1946-06-06; stricken 1946-07-19; disposal 1947-04-10 coded MC/D (Maritime Commission disposal) with MA sale 1947-04-07. Ship note: 'Sold (delivered) by MC to Nicholas A. Kessler, Los Angeles, Cal. Merc. BEAVER (U.S.) 1947, scrapped 1952.' Class data: design 'Navy ATR-1'; 852 t light / 1,315 t max; 165.4 ft oa; armament 1-3"/50 and 2-20mm; complement 51 (1944); 12.2 kts; 1,600 hp; one screw, vertical triple expansion. Class notes: ATR 1-40 were directed 1942-01-19 under the Maximum War Effort (1799 Vessel) Program; the Navy chose wooden hulls and simple triple-expansion steam machinery so small shipbuilders and machine shops could build them without competing with the main shipbuilding effort; one source attributes the design to the John G. Alden firm.

   Finding

   NARA Special List 44 ('by Ship Numbers') indexes an ATR-37 deck-log run covering 1944-09-20 through 1945-06-30. The index start coincides with the commissioned date recorded by shipscribe (1944-09-20), corroborating it against NavSource's 30 September; the end reflects the index's WWII coverage cutoff, not a documented end of operation - the ship remained in commission to 1946-06-06. The companion NARA list of fully digitized deck logs in the National Archives Catalog contains no ATR-hull entries, so this run is a paper holding at Archives II, not online.

   This is an index of surviving log coverage, not the logs themselves and not a commissioning record. NARA states deck logs do not directly document shipboard asbestos; logs would establish movements and assignments - the authoritative answer to this hull's undocumented wartime operating area.

   Finding

   The Navy and Marine Corps Awards Manual (1953 revision), Part IV campaign-and-service-medal ship eligibility tables, contain no ATR-37 entry: absent from the Section 16 engagement-star eligibility lists (other ATRs - 1, 2, 3, 4, 9, 10, 13, 15, 18, 31, 35, 38, 51-54, 56, 61, 62, 77, 80, 81, 87 - appear) and absent from the Section 17 Navy Occupation Service / China Service ship lists (ATRs 4, 9, 10, 13, 16, 34, 35, 38, 39, 51, 53, 58, 62, 72, 75, 76, 77, 80, 81, 87, 88 appear). NavSource's ribbon block for this hull displays only the American Campaign Medal and World War II Victory Medal - a pattern consistent with American-area (continental/coastal) wartime service rather than deployment to a combat or occupation area.

   Limitations

   Absence from eligibility tables is not proof of operating area; the award tables and ribbon display are the only located service indicators for this hull. The American-area reading is inference - the undigitized deck logs (NARA, 1944-09-20 to 1945-06-30) are the authoritative movement record and were not reviewed line-by-line. No asbestos content.

   asbestos_application

   Finding

   Era/design inference for this hull's documented machinery: a saturated-steam plant - two Foster Wheeler 'D'-type boilers at 200 psi, a Prescott vertical triple-expansion engine, and two steam-driven 60 kW service generators - installed in a wooden hull built 1942-1944. For WWII-era steam auxiliaries, period insulation products were commonly manufactured with asbestos fiber: boiler casing and drum insulation, steam-line lagging between boiler room and engine room, valve and flange gaskets, machinery packing, electrical insulation, fireproof/joiner insulation in accommodation spaces, and brake linings on the towing engine and windlass. The wooden hull reduces structural-fireproofing scope relative to a steel hull but does not remove the machinery insulation pathways.

   Finding

   Source discrepancies documented, not silently reconciled: (a) commissioning date - shipscribe prints 1944-09-20 (corroborated by the NARA deck-log index starting 9/20/1944); NavSource prints 'Commissioned USS ATR-37, 30 September 1944'; the Colton yard table's delivery column shows 30-Sep-44. The NARA-corroborated 20 Sep is carried; the NavSource/Colton 30 Sep may reflect a delivery-vs-commissioning conflation. (b) decommissioning and stricken dates - NavSource prints 'date unknown' for both; shipscribe records 1946-06-06 and 1946-07-19 (carried). (c) disposal framing - NavSource 'Sold for merchant service in 1946' and Colton 'Sold 1946 as Beaver' vs shipscribe's documented MC/D disposal 1947-04-10 / MA sale 1947-04-07; the 1946 shorthand corresponds to the stricken-and-turned-over year, not the documented sale. (d) complement - 51 (shipscribe class table) vs 52 (NavSource 5 officers + 47 enlisted) vs 35 (HyperWar ATR class stub). (e) hull construction - 'wooden' per shipscribe class notes and the HyperWar 'Wooden-hulled Rescue Tugs' heading; NavSource spec block is silent on hull material.

   Resolves nothing beyond flagging - documents a genuine multi-source conflict set so a future pass does not silently pick one figure. The 20-vs-30 September commissioning gap is the only materially consequential discrepancy (ten days); disposal-year shorthand (1946 vs April 1947) matters for merchant-chain precision. No asbestos content in any of these sources.

   Limitations

   A negative result in the searched public sources is not proof that the vessel had no asbestos. Undigitized construction correspondence (RG 19), drawing (S39/S48), and deck-log records remain unreviewed; the steam plant makes era-typical insulation materially plausible but unproven for this hull. The hull was scrapped in 1952, so no surveyable structure exists and no museum-era abatement record can ever arise.
