Charcoal grates for large 'old' 27 inch kettle

[GCRAB]

I have been having a heck of a time finding a replacement charcoal grate.  Weber has been useless.  This 'vintage' kettle, est. 1965, has not model.  I can only reference the size.

Welcome! I am sure someone will chime in with more information but it is a 26" kettle. This is a link to the current version http://www.weber.com/grills/series/original-kettle/original-kettle-premium-26. What is the letter on the vent? This link will help determine the age of the kettle: http://weberkettleclub.com/determine-age-of-old-grill/
