It seems that "Wedge Diddlers" may not be a recognized product or category commonly referenced in available market data as of my last update in October 2023. If you meant a different product or category, please provide more details, and I would be happy to assist you with that information!

If "Wedge Diddlers" is a niche product or a term used in a specific industry, additional context would be helpful. In the meantime, here’s a generic template you could use to structure a list of companies in Markdown format once you have the information:
