I assume they are all gone? I just need one to replace the 600 series Perlick that continues to trouble me! - I have two other 500 series and one 600 series - don't like the 600 series.. at least the one I have has given me trouble with dripping! Plus they changed the "P" on the facet! The 600's are a Block letter P and the 500's are a fancier font. I want my taps to match - this is important stuff!
