9 inch south bend with no sn

[largeonee]

Hi I just picked up a south bend 9 inch it has the flat belt drive and the quick change gearbox. it has power crossfeed. it is apart and messed up. I can not find any numbers on it. I looked by the tailstock on the bed and it is blank there are 2 rivets to the right of the 9 inch south bend casting where it looks like there was a tag. any ideas?
thanks

There should be some nimbers stamped in the bed between the ways on the front edge. Maybe the tailstock is sitting on them...Bob
