Well, you won't be disappointed with the ride. I have a mid-80s Battaglin that rides like a dream. My frame is Cromor is a TSD bike. Paint is a fantastic Imron with the decals under the paint. It's a 58 ctc and I've owned it since 1996.
Agree with testing the weld before a redo. Maybe get a pro's opinion. Shame about the fork, hope a suitable replacement can be found.
your frame has a lot of nice details and appears to have been made by a different builder than mine. SLX Is a fun tubeset.
