Gents,

I have just raked through my parts box looking for a few bits and pieces to complete an Innova project and have found what looks very much like an Innova rear sight. However something is puzzling me. As well as the folded piece of metal that makes up the sight body there is a U shaped piece about 40mm long and 14mm wide which is fitted in between the fold of the main body. Any ideas as I have not seem this type before

All the best,

Ken
