Need in tune shakahuchi

Hey folks more than 20 years ago a bought a companion flute with my carl abbot blowing zen book and tape. I am looking to get back into the hobby but I want an in tune tune shakahuchi. Can y one suggest the right key and an affordable price ?

not the brightest bulb so pls reply to

If it’s a shakahuchi it’s going to be one shaku eight sun or 54.5 cm and blow in the key of D. I have one I am willing to let go of for $1,300 that is worth quite a bit more but I never play that one any more.
