WTT Halloran Double Glass. Call sounds great and in very good condition. Bought from David Halloran last year. Only reason for trade is I have another double glass that's personalized. I also have a Stuckey Marblewood. It seems to be a denser wood and brings a higher pitch to calls. The other striker is a Halloran waterproof. I'm looking for a Halloran metal mouth II, Halloran top shelf ceramic, or a Lonnie Mabry slate. Only looking for calls in very good condition.
