The following excerpt is from "Gellerman's International
Reed Organ Atlas":

  LUNDHOLM, C.A.V.; Hamnagatan 28 in 1897, Jacobsbergsgatan 39 in 1903,
  Stockholm, Sweden; established in 1870 by Carl Adam Victor Lundholm
  (1846-1935) initially as a piano store, later manufactured harmoniums.

I assume the organ in question is a harmonium (reed organ) and not a
pipe organ.  J. P. Nystrom of Karlstad, Sweden, made a self-playing
suction reed organ called the Reform-Organ which used a cardboard disk.
