Ephemera - Unknown football team

Can you help identify the football from this unmarked and undated contemporary photograph? The principal clue is the presence of a double-headed eagle on the shirt badge. According to Wikipedia, the double-headed eagle appears as a part of the state symbolism of the following countries: "

• Albania
• Austria-Hungary (historical)
• Austria (1934-1938)
• Byzantine Empire (historical)
• Greece (1925-1926)
• Holy Roman Empire (historical)
• Montenegro
• Republika Srpska in Bosnia and Herzegovina
• Russian Federation
• Russian Empire (historical)
• Serbia and Montenegro (historical)
• Serbia
• Kingdom of Yugoslavia (historical)
  • Kingdom of Serbs, Croats and Slovenes (historical)"

The lot was purchased in Fife or Tayside and we would suggest a Polish connection as an initial line of enquiry. Was the double-headed eagle not also used on club shirt badges? We don't know.
