WW1 heroes, pair of preserved carrier pigeons

  One pair of preserved carrier pigeons in-cased in glass and wood. They are said to have provided communication service during WW1 and were deemed as "war heroes". The birds are identified by dated and numbered leg bands and a plaque which is inside the case.  The plaque reads: Old 76 and 89,  birds by late- Wm Chadwick Died in lofts of John and Sal Caligiuri .  Bird # 89 has 2 leg bands on the right leg.The lower band is from the NURP (the National Union of Racing Pigeons) and the upper band is from the NUHP (the National Union of Homing Pigeons) both date from 1914.   Bird # 76 has a band on the right leg from the NURP and one on the left leg from the NUHP, both dated from 1911.  There is a book that was given along with the birds that identifies and describes these pigeons as war heroes however, it is currently packed away and not in my immediate possession.  I do understand though, the book is still available to purchase in the book stores.  It should be titled " Pigeon War Heroes", or something along those lines.  If this is not something thats fits into the category of this type of appraisal I would be interested in obtaining (in your professional opinion)  the resources  best suited for this artifact.  In my (unprofessional opinion), I believe these birds qualify as museum quality and should be displayed such.
