Early 1970’s instruments will often have a straightforward number on the keybed, under the keys.

In some instruments, like the non-hybrid 200A portables, this is a pretty easy number to access: Just lift the lid! If the speakers are attached to the amp rail, you may need to sneak a camera at a strange angle, or wait until the amp rail is removed. is on the back of the speakers! I find that sometimes –rather often, in fact– this is the latest date in the instrument.

The other most important date, especially if there is no handwritten CM/RT date….

Either CM and RT didn’t make the move, or they were taken off instrument-tagging duty. At that point production tripled for several years. Instruments with an “L” will not have this date: That letter means they were assembled in Logan, Utah, after operations moved there in 1972. I don’t recommend this unless you have other reasons to take your Wurlitzer apart, and you know what you are doing.). (Note–as this number is under the amp rail, it will take significant dis-assembly to reach it. It will not include the year, but that data can be found in the other stamps. Without fail, this will be the latest date in the instrument. They will be accompanied by an initial: usually “CM”, but sometimes “RT” or “RP”.

200 series instruments (pre-“A”), from 1968 through 1972, with no “L” after the serial number, will almost always have a handwritten month and day on the leftmost key, under the amp rail.(Those last “X” digits are a sequence number to differentiate each part.) The year-digit ( Y) doesn’t include the decade so, Augkeys will be stamped “ 6 08 31XXX,” with the “ 6” meaning “197 6.” You need to know the span of years in which your instrument was produced to interpolate the first 3 digits of the year (in other words, “196-“, “197-” or “198-“). The keys and main action rails will be stamped Y MM DDXXX (colors my own) sometimes a digit at either end will be smudged, faint, or covered. I had a Eureka moment a few years ago, and figured out that, by late 1962, all Wurlies used a consistent, encrypted date-stamping system for production of the keys, the action rails (where the damper arms and hammers are mounted), and sometimes the keybeds.Handwritten dates on the lowest “A” key (1968-1972, non-L instruments) are especially useful.

Please check action rail, keys, speakers, transformer, plus keybed, capacitors/tubes, the amp itself (which is sometimes stamped, especially on later pre-A 200’s). Since each date stamp is only for a given part, and parts were stockpiled, we want to know ALL dates in your keyboard (AND its serial number) the latest date found is the most useful date, and will generally be within a couple months of the assembly of the instrument– but please send all of them. Look as well for any light stamps next to the model number, like an “A” next to an inked “140” or “145.” We want to know the model number and the specific serial number, including any inked or stamped letters like “L” or “P”. In earlier instruments, especially portables, this may be on the back or side panel. In a 200 series instrument or later, the badge will usually be under the keyboard, on the left side, near the 1/4″ jack(s).

First of all, find your serial badge and take a good photo of it.

This information, once it is decently un-crude, will allow people to know, within a reasonable range, the year of their instrument simply by knowing the serial number.
