Photo 1 is remanufactured Model SBs installed on remfg. stalls. 

Photo 2  TechForAg Model SBs installed on new TechForAg ProTime I stalls.
Photo 3 shows the Arm in milking position.These arms are rigid vertically and flexible like a cat's tail horizontally - if the cow moves the arm follows perfectly.
Photo 4 (b -l) shows Arm in rest position. Claw hangs straight - rest milk in claw and milk hose does not spill on cow platform.
Photo 5 -Top Outlet Claws work best with Arm TakeOffs; J-Hook on left supports hose bundle, supporting the extra weight that leads to squawking of the front teat cups if it is not supported.
Photo 6 - Spring loaded Auto Clutch protects the arm. If a heifer gives the arm a good whack the outer plate rotates against the rubber spring and the arm instantly snaps back to level position
These are 3-Link 12" Arms, which work best in 45" stalls. 4-link arms are available for special cases. An example would be if you were to milk a mixed herd of Holsteins and Jerseys. TFA also offers 3-link and 4-link 9" arms which work best in stalls with 38" cow-to-cow distance.

Photos right side:

1. Front end redesigned with stainless steel parts. The original was plastic.

2. HERITAGE valve - heavier and with fewer parts.

3. This button resets the Start-Up Timer to 0 in case you have to reattach
.
4. Adjustable end-of-milking timer. Timing volume is changed by adding or removing chips.
1. Your frames are galvanized and subject to rusting. Model SB come with all-stainless frames, whether new or remanufactured.

2. Your covers are made from 22 ga sheet metal and have square corners. Model SB Frames are 16 ga and have rounded corners.

3.The original machines had '3-Roller Vacuum Shutoffs', causing occasional bacteria problems. Model SBs come with hose squeeze valves

4. Your machines may have 'Counter Balance Cylinders' inside the square tube.for height adjustment. The new ones have Counter Weights outside the square tube - way easier to operate and absolutely consistent.

5. There's a heavier J-hook between the first and second arm Link. The original J-hook bends when kicked often enough. We also added a protective washer on top of the J-Hook to keep sand out of the smaller bushings of the first arm link.
If you are milking with original Germania Model Bs from the 70's and 80s, there are other issues to consider:
6. The original frames had a weak spot: If a heifer got hold of the arm, she could twist and distort the entire unit, SB frames are reinforced to eliminate that possibility.

7. You may still have galvanized square tubes. The new ones are stainless

8. Your machines have a friction clutch to let the arm break away when kicked. You have to push it manually back into position. The new machines have spring loaded clutches that spring back on their own (See above) 
9. To service your machines you loosen four knobs and remove the cover. The new machines have hinged covers - loosen one knob and swing it open (Available with new machines only, not for remanufactured units).
