There is no metal stamped indented number that I can find on the aluminum. It measures 27" x 1/2". It seems that the pulley system is jammed up, but would rather replace entire piece as I don't know if I can take it apart without breaking more of those small pieces. It looks alot like the 27" S380 with a 19-005 or 19-002 top and 15-005 foot. The only difference I can see is the channel balance top is not exactly like either you have in catalog.
