The 1831 LM-1 Re-marriages
The 1831 LM-1.1
The key pick up points on the LM-1.1 are the top loops of S-1 and S-2 on the reverse. S-1 will be clear and S-2 will just start to fill.
The 1831 LM-1.2
With the LM-1.2 the top loops of S-1 and S-2 have filled and the top right of T-1 fills.
The 1831 LM-1.3
