This piece appears from time to time on ebay in Germany.  The chap offering it
can't find anybody to buy this wreck.
1. It is an incomplete periscopic sextant, not an MA-1(earlier offers did show
more pictures) and it is stated so in the offer.
2. It is obviously not a Kollsman but a predecessor. In Peter Ifland's
book "Taking the Stars" on page 175 is a picture which shows on the left
a "Burton Manufacturing Company" sextant that looks close (at least from that
perspective). This assumption is further supported by the partnumber "MS Part
No. MS 28011-1" which is stated in the ebay offer as well as under the
picture in Peter's book.
