storm drain basin "Metal" Insert

This is two HO Scale Culvert Metal insert parts, held together by a sprue.  They need to be cut apart and will require a quick, light sanding.

​These inserts are to be used with storm drain basins I have available separately.  The storm drain basins include cobblestone basins and cast concrete curbs.  The curbs and basins are designed so the "HO Scale Culvert Metal Insert" can slide in.  This allows the "metal" insert to be painted with crisp colour separation from the cobblestone and concrete parts; I like a dark weathered cast iron look.
