We have the same problem in that we have, in our collection, some common items in fairly large quantities, for which there is little or no information regarding provenance. Much of this material finds its way into our "living history" collection, where it is used in school and re-enactment programs and is deemed to be expendable. Lately, we have been renting (for a nominal fee) boxes containing selections of such material to teachers, for use in their classroom teaching. I only wish we had a greater variety of artifacts, as this program is proving VERY popular. At the end of the day, though, we still have odd material for which we can see no use, and this we feel free to dispose of through gift to another institution, or trade, or sale on the open market. It seems to me that, if you get a replacement set of wheels that fits your need, and the set you are giving him is of no great value or significance, why not? Harry Needham Canadian War Museum
