Hmm...a wee bit of gratuitous dumping on museums and tax credits... FYI , yes it needs to be appraised,not a problem. An appraised value of 10K will generate,depending somewhat on your taxable income, the 'lame hass' [sic] sum of 4300 and change[ that's for BC}]. Also FYI once prohibs are transferred to a Museum they can only be disposed of with the express approval of our CFO. As far as dewatting goes that execrable practice is the reason why I founded The Dominion Ordnance Museum Inc.over 10 years ago. We are currently working on the construction of an interpretive centre for our collection,all of which is LIVE. With the current regime in Ottawa we could very well end up being the only place in Canada where you can experience a Lewis or a Bren,Sten,etc.,etc.
