Ring spanner, Whit.
A Whitworth ring spanner from the factory toolkit, also known by its older part number D370.
This is a Whitworth ring spanner, part number 60-0370, listed with the older alias D370 in the factory books. It shows up in the toolkit sections of the parts catalog, alongside battery, air filter, and pillion footrest listings, which tells us it lived in the factory tool roll rather than bolted anywhere on the bike itself.

A ring spanner like this is a closed-end wrench, sized to Whitworth thread standards, meant to be carried with the bike so an owner could handle roadside adjustments without hunting down a separate tool. The catalog record spans appearances from 1964 through 1970, but we don't have a specific model tied to this listing beyond that it belongs in the standard toolkit assortment.
If you're trying to fill out a toolkit for a period-correct look or just want a spare Whitworth ring spanner on hand, this is the one the books call for. Give us a call if you want help confirming which tool roll or model your particular catalog entry lines up with.
