^Good point^
AFAIK the group mentioned previously is primarily a non profit volunteer group, to qualify for tax deductible status with Revenue Canada they have to adhere to thier constitution and follow accepted practices within the museum community regarding disposal of donated items that tax deductible reciepts were issued for. If it's anything like the museum I was involved with they can trade between like organizations, if the artifact isn't deemed to be of significant historical value it shouldn't be an issue, but if part of the accession agreement with the donor specifically states it's gotta stay there they're screwed. Time to form your own museum or make friends with another similar organization that can do some 3 way trade deal, wouldn't be the first time either has happened. Or consider investing some volunteer time, you'd be suprised how nice the higher ups get when they find someone who is willing to sweep the floors and take out the garbage instead of the common bored guy who shows up and wants to immediately be a driver, pilot or head restorer without all the dirty work, you never know, you may even learn something cool from the seniors there.
