Wow, what a great gift! I wish I could get that frame from you! That is actually a really simple frame. The side pieces are to hold the thing up, while the horizontal ones are the ones you attach the quilt to. You tack each end to one of the horizontal peices ,and then as the quilt gets done, you roll it up towards the center...does that make any sense?
this is the kind of frame my grandmother used...and I wish I had one!
