I don't know where this plate came from. I got it in a big lot with blue
and gray track. I can't remember if this lot also contained some waffle
plates or I got those somewhere else.
On one of the small sides (2 stud wide) there is a small pit which seems to
be the injection mark you mean. In the bottom tubes there is some text:
(1) (B) ( ) ( ) ( ) (Pat) (pend)
But these texts are not at the same angle. 'Pat' is somewhat upsidedown in
relation to 'pend' and both are not in a right angle with the plate.
Searching in the sleeper plates I haven't used in my current lay out I
found at least another two. These have a (3) and a (6) in stead of the
(1) in the first plate. The texts (Pat) (pend) (B) and the numbers are all
at different angles.
