When R & M Imports was still in business I did order three replacement bells for a 294 9-Bell. As I recall, even though he was semi-retired at the time Randy Thatcher got involved in taking the order. He needed to know the length, diameter and hanging hardware. I imagine that their bells were made to order. Either a complete set, or individual replacements were available. That must have represented some exacting methods with skilled labor/craftsmanship. Folks like that either retire or move on to other things.
According to a very well informed member here, these folks have a lot of existing inventory to liquidate before they can consider gearing up to manufacture batches of new parts. If or when that occurs, the parts will likely have to be made in some other Country. Perhaps China? Americans are mostly consumers these days.
There was a post card from them in my mailbox yesterday; they got my name and address from somewhere so others who are NAWCC members may also get the post card. I may have ordered from R&M in the past and think there's a catalog from them here somewhere, but don't know where it is.
