Not sure if they knew what they were stealing or not.
On one hand, big LF cameras look expensive (and they are, new), but on the other hand they drop rather sharply on the used market. I just got my Toyo 45D for $150. A new 45Gii is over $4k at B+H, but there's some second-hand on fleabay for under $400 (from Japan, nothing from melbs showing up yet).
So unless this particular thief has a client in mind (who doesn't want second-hand but somehow is ok with stolen) or is going to use it themselves, they're going to have a hard time off-loading it...
