Brooklin Models make a 1947 Wesley Slumbercoach in their 1:43 range:

which is a perfect match for their 1946 Mercury Sportsman convertible:

though of course Bev will prefer their 1952 Shasta Airflyte:

whereas I think Gage will prefer their spedboat that looks like it's stolen some ideas from that 1957 BellBoy Bikini:

though personally I'm very taken with their stunning 1956 Willerby Vogue fiberglass caravan:

If you're tempted, the US agent is Brasilia Press, IN.
