I was looking at this post over at turbobricks:

and he posted his production plate, and it doesn't add up. He was showing off his "new" 122(which looked like a great find). I was going to email the guy and tell him to verify the chassis number on the production plate to what is stamped onto his body, but I thought I would get the information confirmed first.

I looked up the info on the volvo world site:

http://vlvworld.com/indexframe.html?production.html

Under the "Type" : 12246VG

It would break down as 12, 2, 4, 6, V, and , G

"12" - would be for a 4-door (the car is a 2-door, it should start with "13")
"2" - would be for a dual carb
"4" - would be for US Export
"6" - would be for a BW35 auto tranny body
"V" - would be for a left hand drive body
"G" - would be for a 1964 production year

Under the Chassis number "Ch. Nr.": 157683

For a 4-door, it would fit the 1964 production year, and for a 2-door, it would fit the 1966 production year.

Under the Upholstery Codes "Kladsel Upholst": 157-258

All 4-door models start with a "1" and all 2-door models start with a "4"

Looks like somebody switched production plates from a 4-door?
