Help needed with Sachs freewheel

Hi, hope this is in the right place as this is my first post here.

I agreed to fettle my brothers v-old road bike which has a 6-speed Sachs freewheel which needs removing so I clean the hub out.

I seem to have most sizes of splined removal tool but not one small enough for this.

Is there anyone on the forum in the Guildford/Woking area who has such a tool and would be prepared to lend it to me for a few days?

Thanks
