Kew hobby 80-1 power washer body*
*This is the main gubbins of the unit & was working fine when last used ~15yrs ago.
The lance comes with it, but is not up to scratch.
The hose/lance is a problem: the lance handle (“A”) was disassembled to replace the broken plastic coupler “B”.
The parts for “A” have been misplaced & /may/ turn up, and even then may not be complete.
The whole repair project stalled 15yrs ago as two parts (aluminium + brass?) had seized together.
The plastic coupler part should readily be available on eBay. I bought one 15yrs ago, but have since lost it. The original broken part is still in place.
