Do both match. The one I found on CL I didn't buy, I just asked the seller if he could tell me what the SN was and what components it had, because I knew that the database was lacking the late 70s models. Does the catalog say anything about the serial numbers, because I guess the one I own is a year older because the serial number only has three numbers.
Do you have that catalog scanned, I'd love to take a look at it.
