We currently have 8150 items listed in the inventory, in 3266 different locales. This abandoned donkey boiler is off the side of Hwy 130, West of Laramie, Wyoming. It is not in the database.
The Method to our Madness
We have started the database by adding major "items on loan" from the National Museum of the Air Force and the National Naval Aviation Museum. We have now branched out to the the other Armed Services and museums. If we had our way we would have the inventory of every museum in the world. Unfortunately I don't think our site provider can support that.
We pad our identification numbers with zeros in order list them in order. If the items is ex-military we also add the associated service(s), ie 63-12201: USAF or WD592: UKRAF.
A lot of aircraft started life in one service and were transferred to other services. For Example: the PBY-5 "046582: USN; 6520: FAB" started as a USN Catalina and was transferred to the Brazialian Air Force. Certain oddities eventually show up, for instance: "42-085082; 084962: USN." This Harvard/SNJ/Texan had an administrative serial number assigned by the company and was built on the line for the Navy.
See our abbreviations page for more information on the abbreviations.
Designations are a constant problem.
United States aircraft: We try to keep the models generic and when drilled down to the item make it specific. For instance, the Grumman Wildcat is either a F4F or FM2 depending on where it was manufactured. In a model search you will only see "Wildcat" and the different versions will show up when selected. For those aircraft that have different names for different roles they will also come out in the model selection. For example the Recconaissance version will not be included with the Fighter version on the listing. That means that you will find five different versions of the F-84 (two under F-84, two under RF-84, and one under XF-84), as each had a different model name.
The US Army is no better, having started their model numbers at M1 for every different type of ordnance/equipment they held in inventory. They renumbered their items in 1962 but you can still find duplications like the M114, it is either a Howitzer or a Command and Recconaissance Carrier. The Army has started with M1 again with the M1A1 Abrams Main Battle Tank and we still have the obsolete M1A1 120mm Anti-Aircraft "Stratosphere Gun" on display in several locations.
One of the big problems in a database view for the Army is their Artillery. In 1962 they updated their model numbers but only added new dataplates on the units during overhaul. Newer artillery units can have up to four associated serial numbers: gun (receiver/breach;) carriage; recoil mechanism; and tube (barrel.) Our US Army reference inventory uses any one of the these as the serial number. ** note: they depend on the end user to record the serial number of the item received. In many cases it is the easiest one found. ** We try to include as many of the serial numbers as we can find in order to ensure we have the right item. US Army motorized equipment has at least two numbers, the serial/construction number and the registration number. If the unit has been rebuilt it will have a second serial number - see M60 Tanks.
