Those behind me in the center panel are 1/48 plastic. My collection is getting fairly large with 260 plastic kit built, 250 kits in my stash. I currently have 170 solid wood models done from scratch and the lumber yard has more than enough wood to last me a life time. The advantage with wood is that the only restriction is where to put them all after they are done. However this will be my last big airplane model. I currently have a 1/144 scale HMCS Bonaventure on the bench, but from here on smaller models will be the norm for me.
