Im about to buy a complete bennett 968 , i think its the same as a 966 as i cant find any info about the 968 anywhere. the pump is complete with just surface rust in some spots and original condition and i thing the price is ok at $900 canadian, one question i have is the top has a plate where the globe would go, i guess it came from the factory without a globe, can that plate be removed and add a globe (is mounting the same on top) also pump has a chrome filter canister on the left side, does anyone know if this was a option on something that was just added on , any info would be much appreciated
