That's pretty close.
For the hockey card, they obviously made single transfers to lay out the plate. And that sheet may have been fairly small.

The T220 silver uncut panels make me think those were done using a larger transfer. Given that the alignment marks are only seen in a couple spots out of all the edge pieces, they either used larger transfers, or erased most of the alignment marks.

The T206 proofs if I remember them right all have alignment marks on each card.

But a large master and a large transfer could have been made

The press in the patent seems to only do single sheets, but with multiples on the impression cylinder all at once.

The Brett press may have been web fed, since the requirement for materials for the silks was X yards of 24" wide fabric.

That opens up a whole new batch of possibilities, like a "sheet" that was a more or less continuous strip of cards, as the plate could have wrapped almost completely around the roller. (some stamps were done on rotary presses that used two plates and the only gap was a pair of lines 180 degrees apart, or one every so many stamps. )

Rotary presses were/are also so much faster that a very large plate might not have been needed.
