Which Model Serotta? Help!

[Latestart]

Sorry for the low res picture. I saw a friend today who was talking about how sad he was and how much he missed his stolen Serotta. Stolen last year from an apartment bike storage in SF.

I told him I would keep an eye for a replacement of the same if he could send a picture. It was a 54-ish size, but it was a gift and he doesn't have the receipt or serial number.

Any help on estimated model/model year?

Sleuths, start your engines.

If anyone has same for sale PM me.

From the decal on the seat tube and the S3 fork looks clearly to be a GS

[edit: sorry, read Serotta but thought Ottrott]

Legend GS?

I used the 'wayback machine' to check the old Serotta website, can't seem to find it on the 2010/11 website. I read elsewhere that GS was discontinued in 2011.

Also only see GS in Ottrott and HSG. Was there a straight Ti GS model? What year?

I am confused. The "GS" line included a Ti bike called Classique, but the frame labels don't match the pictures.

GS stopped in 2011 and that makes sense of 10-speed Ultegra which is what it looks like on the bike (and I believe it is OE). But the "GS" images I find on the web all look like this:

Any pointers? Note that the eBay bike doesn't have the GS sticker...

It’s hard to tell from the photo, but the seat tube and downtube look to be straight gauge, which would suggest to me that the frame is a Classique.
