UPDATE: replacement latches for the Mark V can be found here: http://www.dblittle.com/catalog/product_info.php?cPath=29&products_id=108
When I bought my Rhodes Mark V, some of the case latches which secure the lid to the piano were bent, or missing. I want to replace them, and I only found one source for the specific type of latch I need. Penn Fabrication calls it a “Medium Extrusion Mount Twist Latch“. Here is a diagram of it. Unfortunately, they only sell in orders over $75. Their consumer supplier doesn’t carry the latches either. So, for now, I’m going to try checking at our local hardware stores. I’ll let you know what I find.
