Norton FULL-FLOW OIL FILTER KIT (TO CONVERT OLDER MODELS)
A full-flow oil filter conversion kit for fitting a filter housing onto older oil systems that didn't have one.
This is a full-flow oil filter kit, listed in the catalog as a conversion piece for fitting a full-flow filter setup onto older models that did not come with one from the factory. It shows up in the parts book under the Oil Tank, Oil Pipes, Junction Block, Rear Chain Oiler and Full Flow Oil Filter figure, which tells you it lives in the oil system rather than the top end or gearbox.

The kit is meant to bring an earlier bike up to the later full-flow filtration arrangement, so it includes whatever's needed to route oil through a filter housing instead of the older by-pass or non-filtered setup. Beyond that, the catalog record is thin - it only appears once, tied to 1973, and doesn't spell out exactly which older models it was meant for.
Given how sparse the record is here, call the shop before you order so we can confirm this kit matches what your oil system currently has and what you're trying to convert it to.
