A contra I used to call reasonably often 10-15 years ago popped into my head the other day. I can't find it in my cards, which makes me think the reason I stopped calling it is that I lost the card. Can someone ID it, and tell me what the B2 is? (I'm gonna guess R&L through, circle 3/4, pass through, but there are lots of possibilities.)

A1  Current neighbors right hand star; previous neighbors left hand star

A2  Dosido current neighbor 1-1/4 to wavy lines; balance wave; allemande R 1/2; allemande L 1/2
