Default Re: Any info on how to use Relay gauges BGT No.1

BGT 1 would be box's guage's tension number 1. and you needed two of them. The strap under the lid was to house the extra long detents. Each guage had both a horizontal and a vertical detent held to the side on a fitting. The hole on the tip of the detent for calibrating with a set of weights. happy days. Cliff.
