Production date?

Is there any way to find out what the production date is for a OP-1 (serial #, etc.)? I bought mine used and have no idea what the original date is.

no I believe the scramble the serials. @punji was collecting serial numbers and purchase dates to figure it out. what’s your serial? also don’t send the last two digits… for example 01232xx.

Where would the serial be located?

Unfortunately the serial numbers and corresponding purchase dates we collected were lost, I was unable to recover them in the Google cache… :frowning:

The serial number can be found in the white sticker attached to the original paper box and also inside the OP-1 at the connector board that may be reached from the small plastic panel at the back.
