I am in need of two diamond shape levers for a C.S. 388 and 73. I think they were the diamond shape levers, would anyone have any idea where i could get them??

Just so as not to confuse people, the lever paddles are actually round but have an embossed diamond containing the CS logo.

Because the pens are not high value, I doubt many repairers would keep such items in stock, though you could e-mail all the online UK vintage CS suppliers to find out. Otherwise, all you can do is look out for cheap black or broken examples of the pens for breaking on ebay, at pen shows or antique fairs.

Don't be tempted by similar pens having levers apparently the same size - the pivot points are often in different positions which means they are not always interchangeable.
