Calcium Carbide bins (Flatcar load) for your garden railroad 1:29 scale

I've made these Calcium Carbide bins for my 62' low bulkhead flats but they would be an interesting load for any modern flatcar.

To secure them with the top rack I used 4.5mm (11/64") Outer diameter springs cut into smaller pieces.  2mm chain fastened to eyepins and inserted through tiny holes and bent over.
