Early 80s Japanese Sigma by Martin D5s lifting bridge Part 2

This is from the last run of Sigma in Japan before Martin moved production to Korea. In 1979 they stopped using paper labels and started stamping the back brace in the same style and manner as they did in Nazareth. This lasted until 1983 when Japanese production ceased.
In this video I finish off after re-gluing the bridge, shaving it to get the action down as it wasn't high enough to justify a neck reset.
