Maybe a variation on the 13th Engineer Regiment ... Or not? Still a neat WW I Engineer patch,

Could be . There are 19 stars, could it be 19th engineers?

Like your thinking, do not think related to 13th

I'm kind of leaning toward this may in fact be a variation of the 18th Engineers, based on color of background star field in place of sun burst and the castle being red with white high lights (?) condition kind of hurts with ID but a great patch none the less and I'd snap it up in a NY minute...George
