The lacquer is truly shiny and without any damage. Likewise all the chrome is without any blemish. the decals are immaculate. The machine was not polished-up in any way, only lightly dusted off.
This belonged to a typewriter repairman who ran his own repair-shop. It was one machine that he kept for himself - perhaps a customer trade-in. Judging by the state of the machine and the fresh platen, he probably serviced it and then only used it very little. It was clearly stored well in a dry and warm spot for 40 or 50 years until it was bought from the repairman's descendants and picked-up yesterday.
The one plastic spool that was probably put on the machine some time in the 1980s will be replaced by a matching metal spool. Other than that, it will not be touched. Rather it will continue to be stored warm and dry and sometimes be used for typing (with care).
The serial number 702222/M makes this a (late) 1938 machine.
