A good old saw. I had one for a number of years. Sold it to my sisters father in law. Now, my brother in law has it.
Mine had cast iron wings, but the skeleton style.
If I had it today, if available I would look for solid cast iron wings. If not available, I would just make wings, like the Biesemeyer extension tables that come with the fence kit. A friend bought a used Unisaw about 6 years ago, and I used it a lot. It wasn't untill I found a used Unisaw of my own, that I realized that on the right side of his saw, there was no wing, just an extension table. There was no downside to that setup.
Again if I still had the saw, I would put a Delta T-2 fence on it ($150) Unless a $150 Biesemeyer fence came along!
The fence would be a great improvement on that saw.
Good luck with a good old saw!
