Some of you may be familiar with collector Anthony Lawler. He was a good buddy of GRs and had amassed a house full of "display" models. George Hamlin says many of these are now on display in the Museum at San Francisco airport, SFO. You might want to drop in and take a look. Even without the models it's a fine museum to visit!
