Well I hate to sell this but here goes..... Eldon made several lap counters back in the 1960's but this was by far the best one. It worked well and you did not need those little counter pins inserted in the car chassis to trigger the count. I purchased this, took it apart cleaned it glued the rotary window numbers back on and fully tested it. It works great. The countdown timer is integrated into the lap counter so you have a timed and lap function integrated into one, once the timing ends the laps indicate the winner. Neat technology for the day. Stamped 1965 on the bottom. A very vintage and working Eldon counter. See the photos. USA sales only and parcel post to keep costs low @ 2 lbs shipping weight.
