The bottom one would be from before June 1998 when the 323 area code was created.?
BTW, if you wanted a G-11 for Christmas in 1998, it was $3400, with a tripod and digital drive controller; no Gemini available. Given inflation and the various enhancements, today¡¯s prices are pretty darn good.?

There is a serial number at the bottom of the RA axis.? ??
The company must have a way of deciphering that into the mfg date.??I think the first 2 digits after the initials HGM indicate the year of manufacture.??
The bottom photo shows label HGM9602012 so likely it is from 1996 .? ?That is my oldest version badged Celestron G11 ("CG11").??
The middle picture shows a "Losmandy G11"? RA labelled HGM138135 must be from 2013.
The bottom image is a GM8 RA labelled HGM076064 so I think it's from 2007.
Best,

I may be able to call in to get the date of manufacture of my G11 but it has a black ring gear and is a gem-1 with the last version of the hardware. Standard un-tucked motors.
I'll confirm the worm gear and bearing arrangement tomorrow. It does NOT have space for a wavy washer between the clutch plates.
Does that put it in the 2005 time frame.??
