Although they came with a dozen pins, none are left with this and you will need to make at least 2 to demonstrate the clock's bell ring feature. To quote from the Howard catalog; "The dial is made in such a manner that pins can be inserted to make contacts at any 5 minutes of the day or night, and transmit electric current for ringing bells or making other signals." The weight baffle is replaced and the pend tie-down is new; otherwise very good original condition; orig tablet touched up in red area. Ht 32"
