Hi Dave,
I just checked and there are no plans other than for Goose #2.
I got the overall plans for one of the 3-truckers from somewhere in an add in NG&SLG. My drawing says Baby Grande Western Balsam Shops. I never seem to remember the current owner's name and web site.
Based on the 3-trucker plan, my photos, and dimensions from Annual #9, I have partial plans for Goose 7 in 2.5" scale. I have one of the three trucks built and I had the frame built (altered for 40' curves). However, I am reconsidering the frame and planning on some alterations.
I did get a great hint for the headlights. A fellow built #2 and used the LEGG's containers for the headlights. LEGG's no longer uses the silver egg shell container, but each Easter you can find something like them at CVS and the Dollar Store.
