Nice custom made model box... unfortunately not a real model kit. I've seen a white '63 Fairlane wagon one too... Still, there is a new '49 Merc woodie kit coming out...and there are several resin wagon bodies available to convert other kits (and sometimes complete car kits in resin).
Heres a link to what I expect is all the current 1/25 scale resin wagon model kits available. Lots of 50's, 60's and 70's wagons that were never mass produced. No 68 Country Squire but there is a 67 Ford Country Sedan wagon. Lots of wagons in the list with links to photos. http://www.rocketfin.com/resin_search_results.cfm?PageNum_items=1&search=wagon There are several Fairlanes including a 63 Fairlane wagon. and a 67 Belvedere wagon like mine.
