Sounds to me like you guys are looking for a benefactor for the project such as a corporate sponsor, group or private individual.
Always worth a shot to try Ford Canada or maybe the local Ford dealer.
Unfortunately these days, most sponsors seek some sort of recognition from their donations, whether it be through advertising or financially (eg tax receipts)I could see the local Ford dealer wanting to have it available for loan for promotion or advertising...
I think that your group may be in for a hard sell as it usually comes down to "whats in it for me" mentality.
Most museums have an extremely difficult time in extracting funds from government sources let alone the generousity of the public, hence the poor quality and conditions of most museum displays.
Just a question and maybe none of my business but I'll ask anyways...
Why did you guys decide to undertake a project out of your own pockets rather than having the appropriate funds raised ahead of time?
If the Legion has endorsed your endeavour shouldn't it be the members financing it???
