It is in this phrase: Since the Victorian period where policemen had a simple stick made of wood till the ceramic telescope, the baton lost its place. It is for a translation - thanks.
Do you know why the air suspension failed? It could be a simple fix.
Yes this can be done just be sure and diable the pump
From the web (ceramic telescope) it seems that ceramic mirrors for telescopes are available, Are you sure the piece you have quoted is not a machine translation as I can see no connection between a police 'simple stick' and a telescope. In Victorian times a policeman carried a nightstick or truncheon the latter being issued up till the more modern batons and extending batons. I think you piece has led you on a wild goose chase.
