I have a number of slingerland TDR strainers including two with the butt. I have another 7 or 8 of the strainer with the back plate and one or two without the back plate. On Ebay I have seen people sell parts from the strainer and ask ridiculous prices. My strainers are complete. for the strainer/back plate alone - $80, for the strainer/ back plate and butt - $120, and for the strainer without a back plate $60.00.
