You've got me beat.
I bought a $5 sewing machine yesterday at a rummage sale. It's in a case and weighs a ton. I've not looked at it yet. Kid at sale carried it to the car for me and it may stay in the trunk a day or two until I get the nerve to try to pick it up.
I wanted another machine for our church group. Hope it works well and is not too heavy to deal with. The heaviest
monster I've ever tried to move.
