Serial Number 5481815 was reported as inaccurate.

Note: If I correctly read Michael Chamelin's book, page
214, the total production of the 161A IIB would be
in the 5300-5400 range rather than the 700 which
would only reflect the first run in late
1931-early 1932.
Curator Response: Absolutely correct. This run should be designated as "161A" instead of "161." Thanks for the correction. The database has been updated accordingly.
