after all, the end-user (contractor) had no money for such expensive machinery. And, what with the DoD buying loads of machines. they completed thousands of machines, often mainly 'toolroom' models as the initial requirement would be for making tools, and the subsequent requirement would be for production. another one was Electro-Motive Corp (now Electro-Motive Diesel) for construction of naval submarine, transport and landing craft diesel engines. Monarch was one of the very first companies to be placed on 24/7/364 operations (probably a day off for Christmas). As the machines left the erection hall (final assembly) the original sequence number and the date of completion would be stamped on the machine. Monarch would assign those 100 sequence numbers immediately upon receipt of the order. Say, the DoD ordered 100 10EEs, and specified a delivery schedule which was convenient to it. You should find lots of groups of sequence numbers which refer to identical machines.

Plus the model identifier (EE, etcetera).

Monarch assigned sequence numbers, not serial numbers.ДЄs Production Control received an order, a sequence number was assigned, sequentially.ДЄs machines were completed, perhaps a year or more later, the sequence number was stamped on the machine as its serial number.

The serial number table which I posted is not fool-proof. It takes a lot of amplification to move a turret with three 18' guns. Probably a lot of naval fire-control systems, too. The B-29 (defensive) fire-control systems were all Amplidyne-based. Oh, yes, the navy used AmplidyneВ®-based systems, which are like WL-S, but with a very much higher amplification factor. What you gain with an electronic drive is efficiency (almost no power consumption when idling, and, obviously, no M-G noise).ДЄ competent radio technician could fix a WiaD, but an M-G repairer should know a little about rotating power amplifiers. What you sacrifice with an electronic drive is serviceability, unless the customers are specially trained. What you gain is customer familiarity with these systems as all kinds of elevators and hoists (and equivalent devices in a naval setting) also used the WL-S. What you sacrifice with the W-LS is efficiency. The official changeover from Ward-Leonard System to WiaD was 1949, but customer demand kept the W-LS machines rolling off the production line a LOT longer than Monarch had anticipated. There are bound to be apparent exceptions, particularly on so-called 'War Baby' machines, as some of those were scheduled as dozens or even hundreds of otherwise identical machines at the beginning of a period, with individual examples coming out of Monarch's erection floor when they were ready for shipment.ДЄnd, in those times of particular economic and political stress, world-wide, parts remaining from otherwise old stock may have been used on a new machine, which accounts for the crossover in 12.0' and 12.5' EEs and the various versions of M-Gs, DC Panels, and WiaDs.

Of course, this doesn't account for bed changes, but that's to be expected. Given those two facts, Monarch can, within reason, respond to questions about and requests for prints and parts. The number stamped between the Vee and Flat way, at the right end of the machine, will always indicate the model and the sequence number. The serial number plate affixed to the frame indicates a lot of interesting facts, sometimes including the value of the machine, and often the actual date of completion.

The sequence number may or may not indicate when a machine was finished, as it is a sequence number assigned when the manufacture of a particular lathe order was accepted. (I obtained the table from a source believed to be reliable, but I have not checked that table with Monarch).ДЇrom the sequence number, one can tell within a few weeks of when Monarch's production control department committed to making a particular machine. begins a very old thread on serial numbers, which are, in reality, a model code, EE, etcetera, followed by a sequence number, usually four or five digits.
