1957 to 1960
Ink stamped number on back top of the headstock.
The ink stamped number consists of 5 digits, where there is a space between the first digit (representing the last digit of the year) and the following 4 (chronologic serial number). If there is a 6 digit ink stamped number, there is no embedded space as the serial number has exceeded 9999 and now occupies the place where the space existed in numbers 9999 and lower. No space and 5 digits following the year
only occured in 1959 and 1960. Production in 1959 and 1960 was in excess of 9999 instruments so "9 9999" was reached and the six digit scheme can be found as follows : "93nnnn" It is assumed that they reached approx."93200".
