You can occasionally see Chesapeake Model Designs at the Eastern US model shows. In February 2012, I saw them at IPMS Richmond and bought a few items from them. In 2011 they were at AMPS International in F-burg. Beyond the occasional show (and not sure how to know which ones they will be at), I am not sure how to contact them. I know that Chesapeake Model Designs is no longer supporting their weblink
And, from talking to them at the show, they do not plan on re-activating it. Further, they made comments that they may eventually get out of the business side and back to just building for their own enjoyment.
