Your bid is for a BRAND NEW, (new old stock), never used, ESE, model# ES 300, 4 digit timer which uses 4 RCA Numitron tubes to count minutes and seconds, up or down, to 100.00. There are 6 push buttons on the top front for Up / Down / Stop / Min / Sec / Reset.
The tubes are bright and light evenly. It is very hard to tell from my photos. It has been kept inside the protective plastic since the day it was purchased. It's in perfect, pristine condition! NOTE: I wil include a copy of the paperwork which includes description of components and features, operating instructions, circuit description, specifications, disassembly instructions, parts list, PCB layout drawing and schematic diagram.
