Thread: additional triton parts?

I've just recently bought a very good value job lot from a guy who lives about 100k's away, including 2 tables with triton saw and router, rta300,bevel and eta300 ext table

after downloading various manuals I think I have everything sorted

The guy has just contacted me saying he found additional parts if I wanted them, they look like the main rails for the ext table but not the same
the centres of the mounting lugs seem to be about 650mm at an educated guess, which is close to the sliding chassis centres on the ext table

I'm thinking they could be a home made addition but I don't know what for, any ideas?

on the other hand they could have nothing to do with anything
