The four-gap bridge shall have a large and heavy copper strip of SWG No.18 mounted on a heavy 3/4 thick laminated base of size 44x4x3/4. Nine heavy brass terminals lock type are to be provided to reduce the resistance to a minimum. The ends gaps are closed by removable brass Binding pieces, which are held in position by the terminals. The 24 SWG constantan wire is stretchedalong the top of wooden meter scale and securely clamped to the brass end strips so that end errors are negligible.Overall dimensions 1.10m x 100mm x 50mm, including terminals with superior quality spring type Brass Sliding Jockey, which moves on a metal rod, The brass strips are fitted on a laminated board of size 44x5x3/4. Includes detail working manual...
