As it was explained to me with my C&R, I have to hold something I purchase with it for at least a year and can then sell it if I find a better example of that piece or a better addition to the collection. I'm currently waiting to complete an auction with an Inland M1 that is a much better example than the mix master Inland I currently possess. If I obtain it, I will sell the original Inland since I will no longer need it. Since I bought it right at the start of covid, I'm pretty sure I can sell it for enough to cover the cost of the new one and just note the sale in my records book.
