I don't recall for sure seeing a 61OT in that particular box, but after doing some deductive reasoning (without a conclusion), I would say maybe, with no concrete evidence. I think I might have seen one on Ebay, but no proof to back it up.
The 106OT, the 34OTY, and 8OTY all started in 1990, and I have seen those three only in the Mustard (Tan)/Black box like you mention. I believe 1990 was the last production year for the 61OT.
The 89OT began it's run in 1989, and I have seen it in both boxes (actually the 89OT was in the newer one piece wood grain box), so the 61OT ended it's run right at the time of the box change (this might not be true). I'm sure if they had a surplus of the Brown Woodgrain Box, they went ahead and used them up.
Like shields and stamps, us collectors make a bigger deal out of boxes than the attention that was given to them during production.
