Thats strange they did it like that. Can you still use the serial number on the reciever to determine its manufacture date. I looked it up on line and I guessed the date around the mid to late 20s by dividing the number of years it was made into the production numbers. Im sure production numbers weren't the same every year so Im sure my system is off. Any chance you might have a better idea when it was made.
