    I have identified the object using Allen's photographic atlas of
symbiotic variables.  This identification is truely different from
Duerbeck's.  The source reference listed in Duerbeck's lacks a finding
chart.  The position quoted in this reference agrees with Duerbeck's
position.

    Interestingly, these two "candidates" for V4074 Sgr are found to be
listed as peculiar objects.

Duerbeck's object:

  181605.50 -305111.5 (2000.0) 11.1  GSC
  181252 -3052.3 SGRV4074 ZAND 8.6 12.3 P
  181605.4 -305110 (2000.0) SS1-149 13.0 11.5 7 Z AS295
  181605.5 -305111 (2000.0) 1150H    Hipparcos

Allen's object:

  181612.19 -305208.2 (2000.0) 10.8 N  GSC
  181612.3 -305208 (2000.0) PK1-6.2
  181612.5 -305208 (2000.0) ESO457-PN2
  181612.2 -305207 (2000.0) 1094H    Hipparcos

  181611.1 -305150 (2000.0) 167362  (emission line star)

original AS catalog (no finding chart):

  181250 -3053 (1950.0) AS295

  Which is the real V4074 Sgr??
