Not quite what you say you are looking for but I have a genuine K1200S tank bag, in only lightly used condition. Also a Givi Top Box monokey mounting frame, also in good cond. Also a Givi E52 top box, old and scruffy but in one piece and with working lock and one key. Off my 1200S from a year ago.
If of any interest, or need pics, please pm me.
