*Model Garage*
puzzle
(a.k.a. *Spotcheck*, *Blocade*)
shown on page 103 of the
*Hordern book*,

**Slide A While Solution**
Here are the start, every tenth position,
and the end position of an 83 rectilinear move solution
(88 straight-line moves);
pieces are labeled the same as Hordern's book uses for the Model Garage puzzle,
except pieces 11 and 12 are labeled X and Y:

**Model Garage Solution**
Hordern's book presents a 51 rectilinear move solution.
Here are the start, every fifth position,
and the end position of a 51 rectilinear move solution
(54 straight-line moves):

**Model Garage Versions A and B Solutions**
Hordern's book presents Model Garage A where both A,B and C,D must be exchanged,
and Model Garage B that also requires that all other pieces end in their original positions,
and gives the same 213 rectilinear moves
(224 straight-line moves)
solution for both,
where the A version omits the last two moves of the B solution.
Here are the start position and the position ending each row of the Hordern solution presentation:
