Hi. I have a set of vintage Singer sewing machine iron legs, but I cannot find another set similar. The ones I have do not have the intricate criss-cross design like all the others on the internet have. Mine have quite simple legs just with the Singer badge in the middle and no large metal "Singer" sign. What have I got? Thanks!

legs to a sewing machine, sorry could not help myself, I have bought complete non working petal units for 100 dollars or less
so from a money value, most likely very little
