Martin ,
If i was close by I would gladly do your 350 , its a well cared for machine -looks new
but with the packing and shipping it would add a couple hundred or more to the price
and be hard to do - You will easily find a new home for your saw -
I'll keep my eyes open in my neck of the woods - with time one will show up.
The best to you my friend !
If anyone hears about any older 18 inch hegners in the Western NY area let me know-
Tony
