VIN doesn't seem right

Posting this here because it might be related to my other post. Not sure where else to put it. A forum search didn't bring up much.

According to the VIN decoder I have found, the 10th digit should indicate the model year. My 10th digit is either O (oh) or 0 (zero). Neither O nor 0 are listed in the decoder. I'm starting to wonder if I have an European market bike.

Can anyone help me decode this?

VIN: GS550E132088

Thanks, jabcb, but I don't understand how you determined column "T" to be the model year. Maybe the explanation is on that chart, but it's hard to read.

I see now that the VIN and the frame numbers are the same.

Suzuki used a letter to determine model year for a while prior to standardisation. It didn't necessarily appear logical.

Off the top of my head:

1975 = M
1976 = A
1977 = B
1978 = C
1979 = N
1980 = T
1981 = X

So, you have a GS550 ET. If it were a year older, it would be a 550EN.
