[can-talk] Monitoring equipment

The TasmanianMuseum and Art Gallery has been offered some former 
government workplace monitoring equipment for its history collection. The 
equipment was used to test conditions in mainly industrial workplaces 
around Tasmania. The offer includes a box of four steel inspection(?) 
tapers, pictured below, although the donor does not know what they are 
for. They are very heavy, with the largest weighing upwards of 10-15 kgs. 
Each shaft is flat on the small end with a small centre drill hole in the 
middle. The opposite end is curved (rather like the end of a baseball bat) 
and has no hole. Neither the box nor the shafts have any markings. 
Approximate sizes are:

            Length                                      Large diameter    
Small diameter
            330mm  (13”inches)                             25  (1”)    16 
(5/8”)
            430mm  (17”)                                       38 (1.1/2”) 
                 22  (7/8”)
            510mm  (20”)                                       60 (2.3/8”) 
                 28  (1.1/8)
            570mm  (22.1/2”)                                 70  (2.3/4”)  
               32  (1.1/4”)

Does anyone have any idea what these might be?
