The open seat stays and flat dropouts, like this, http://www.flickr.com/photos/16732514@N ... 7354844853
would indicate that this is a '96 or earlier frame. Therefore not a Team SL, which had dropouts like this, http://www.flickr.com/photos/16732514@N ... 993582750/
and plastic caps in the top of the seat stay.
The decals are period correct, except for the Team SL logo. The paint is probably not. Early Dekerfs were at first either metallic green or orange, then red or blue too. White, AFAIK was not an option on these. I think it has probably been resprayed, but It doesn't half look good!
. I was thinking of white pearl for my '94 dekerf, but for some reason chose yellow instead.
When Chris Dekerf sends out decals, he includes the Team SL logo unless it's a softail or other wierdo. It was probably applied in error. Mine was, and now masquerades as a Team SL with '01 + style graphics. Purists might blush, but underneath it's still a Dekerf, and a Ritchey logic one at that, with an absolutely sublime ride (better than the later 853 tubeset).
I can't make it out from the pics, but I bet it has a flared seattube at the BB too...
