[C38] Chainplate replacement

[Max Soto]

Well, 316 it is!!!!!!  I thought that something was wrong with those numbers...LOL
And Marcy, as you said, they are 
 pricey custom creations, unless Catalina has some old stock hanging around......
They were made by Garhauer, but they no longer have the designs.....

Regards, max
