I used to have a CPP and a CPE, but don't have either, now. These are leftover parts, but I don't know for what. Beats me what the screws and hardware are for. There's a cog, a couple decent rollers, three well-used 260mm graduated cylinders and one pretty new one. Grab 'em if you need 'em. No returns on this.
