My thoughts exactly. A car like that, stolen, could go anywhere in the world. I thought FChat would be an ideal place to share this because of the global audience and the right demographic of people to be around such a car.
A friend of mine in Florida who is a racer shared it on Facebook - that's how I learned of it! Share all you can! Hopefully the car will be found.
23s are great cars and "B"s are even more rare. I knew a person who raced 2 and another older gent who had one. A vintage race prep person was trying to convince me to get one years ago. Might be a good idea to also post in racing section and on racecars.com.
