In bicycle frames above size 56, EMC replaced SL tubes with SP tubes, starting from the bottom tube and ending with seat tube (in my frame from 1980 -57cm - top and down tubes are marked SP, seat tube: SL - 27.2 seat post)
TSX is on my shopping list (Century or Corsa Extra) - not available yet.... so I envy you
If this is the E series - congratulations on having EM (Professional); interesting is the designation 08 - impatiently waiting for the photos
