It does. As a french speaker, that article is very inaccurate and does not reflect what happened at all. Reverchon is still in business, has an active website
Reverchon and they delivered a coaster this year to a park in France. They are very well alive, but most bloggers forget they exist since they only exhibit at the IAAPA Expo Europe show and don't come to Orlando for IAAPA Expo in November. I am looking forward to talking with them for the first time next month in Paris.
As for the coaster at Fun Spot America, that one happened after a very strange situation. For the 2004 season, Zamperla and Reverchon had signed an agreement where Zamperla would market spinning coasters to foreign parks and two were sold: Raging Cajun at Six Flags Great America near Chicago (moved to Six Flags America between Baltimore and Washington, DC) and Crazy Mouse at Del Grosso's Amusement Park in Pennsylvania. During the construction phase of those, Reverchon went into the equivalent of Chapter 11, leading Zamperla to finish the rides. So, you have Reverchon built track and cars with Zamperla components and controls. After that, Zamperla oddly started selling their version of the Spinning Coaster with their own style of cars while Reverchon still manufacture the original after reorganizing.
The argument that you can't get spare parts if a ride manufacturer goes bankrupt is false. If parks with Schwarzkopf coasters, like the Scorpion at Busch Gardens Tampa, can still get parts for their rides when Schwarzkopf went bankrupt as a company in the mid 1980's, where is the issue? The Big Apple Coaster in Las Vegas is an orphan ride now with the last one of its manufacturer left in the western world, the american office of that company closing in 2001, etc. Yet, they do modifications to the ride, got replacement trains (from Premier Rides), upgraded the braking system, etc. There are a few companies that will help parks with rides like that, so no ride is truly left alone. Its all a matter of finding the right partner and how important the ride is to the park since it will determine how much the park is willing to spend on it.
