Re: Later 500mm v1 have date code?

Canon stopped putting date codes on most L lenses around 2010 when they went to a 10 digit serial number. Looking on eBay it seems that about half of the EF 500mm f4L IS listed have date codes and half don’t. I suspect that the ones without date codes were made around 2010-2011 and have 10 digit serial numbers instead. How many digits are in the serial number of the one you are looking at?
