This is a frame for a barrier pitching machine (automatic launcher). It was used with the BM-300. It's an old item, so there are rust and scratches. If your frame is warped or you've lost the support pipes, please consider purchasing this. As shown in the first and second photos, one tire is missing, but it can still be moved. It can be disassembled into support pipes, an upper frame, and a lower frame, so individual parts can also be sold. #Barious #Silver Seiko #Pitching Machine #BM-300 #VS-3000
