i like how you give home to all those boxes, most other collectors wouldn‘t even have a proper look at
Picked this up from a boot sale whilst on holiday not my usual bag and no idea what it has to do with aviation but thought it looked cool its build date on its base says 1998, its a Spirit of St Louis, Ryan NX-211 Mk2
