Early Scott Addict size chart

[Clannagh]

Hi
Hope someone can help, I have picked up a Scott Addict frame set on ebay. It was advertised as a 54cm. Now its here I'm not convinced it is a 54, maybe a 56cm no sticker on rear seat tube so can not confirm.
All I know for certain is it uses HMX NET carbon (so not the SL) it has early style graphics. Headtube is 160mm length. Centre of head tube to centre of seat tube is 55cm!
I have googled size charts but they all show later models which appear to be slightly different in design so I can not rely on them.

Does anyone have an early size chart please?

Many thanks Craig

Headtube of 160mm is a size L . My 2008/2009 Scott Addict had an 140mm headtube ( size Medium ). Also my 2013 Scott Foil has a n 140mm headtube.

Thank you PinaRene much appreciated. My suspsions were correct. I'm 5'11" so this large frame should still be a good fit!
