Very nice, vintage set. Complete with everything pictured. All glass components appear complete with no cracks or chips. All graphics on glass tubes also complete and vibrant. Rubber squeeze plungers have hardened with age, but I understand they boiling them will mane them pliable again if you want this to be a working unit. I will not attempt, but will leave that option for buyer. Please see pics for further description and condition.
