Luberto Classic Heavy Duty Sewing Machine. My father was a saddle maker and this was his machine. It's heavy cast iron on a wood table top. All one piece. Pedal or manual sewing for controlled stitching. Works perfectly. Very heavy and will need to be picked up from Pioneertown, Ca. (near Yucca Valley/Joshua Tree) I'm sorry I really don't know much about the mechanics of it but I know it works fine and never had any issues. Purchased new in 2008. Asking $5000 obo.
