Selling a 'Demo' Item to a Customer that is actually an Owned Asset, Not Inventory

Wondering if anyone may have some insight for how to handle this scenario on the GL and the impacts to roll up reports such as the Balance Sheet, Cash Flow Statement, etc :

We have company owned assets that are lent to customers as demo, but we own them, they are not truly demo inventory. What is occurring is that sometimes our Sales team then makes the actual sale, but sells the customer that same demo equipment. The equipment that was our actual asset, not an inventory item.

We could potentially use a consignment inventory approach for when the item is actually sold to the customer, but we're having to log work around entries to account for when the demo (actual asset) item needs to be disposed. We can't use the consignment option for that scenario because it would reside on the Balance Sheet incorrectly, for example. We don't want to consider it Inventory.
