The earliest known Stanton balance, serial number 239. Made in 1946 or 47, no model given but probably a forerunner of the CB series. | 
The beam of s/n 239. |
 A model CB3 (Chemical Balance). This series included simple free-swinging (undamped) balances without optical projection. 200 g capacity, 0.1 mg resolution. | |
Model AD2, the workhorse early analytical balance. 200 g capacity by 0.1 mg resolution (optical), air-damped and weight-loaded to 1 g. | 
The beam of an AD2. |
 Model AD3, nearly identical to the AD2 but only 1 decade of weight-loading, achieving 0.1 mg resolution over a 100 mg optical range. |  The beam of the AD3. |
 Model BA6, the top-of-the-range analytical balance. 200 g capacity by 0.1 mg resolution (optically), fully weight-loaded over 4 decades. |  The beam and weights of the BA6. |
 Model BA9, later version of the BA6 with only 3 decades weight loading and wider optical range. |  The beam and weights of the BA9. |
 Model A42, analytical balance with 200 g capacity and 0.1 mg optical resolution. By the end of the 1950's, grey painted cases had displaced the mahogany finish. Basically a modern verion of the AD2. |  The beam of the A42. |
 Model A43, the modern counterpart of the AD3. |  The beam of the A43. |
 Model B19. Analytical balance with 200 g capacity and 0.1 mg resolution, fully weight-loaded. Modern equivalent of the BA6...9 models. |  The beam of the B19. |
 Model C26, a student's balance. 200 g with 0.1 mg resolution by pointer and chart. No weight-loading but a rider mechanism. My very first balance. |  The beam of the C26. |
