Smoking in Pullman Cars?

[Right Away]

Having never recalled seeing "No Smoking" signs on Pullman coaches, were there ever any restrictions on smoking in these vehicles. I'm assuming that  possibly "back in the day" the premium fares would have allowed passengers to do as they pleased. The open nature of Pullmans would be somewhat difficult to segregate those who wished to smoke from those who didn't.

In the very early days Pullman trains included specific Gentlemen's Smoking Parlours - but in the more 'modern' era of the classic 'K' type cars the interior was often divided into different sized saloons ( maybe two or three seating bays ) in addition to the coupe ............ smoking was, of course, more prevalent then but there must have been areas 'off limits' .... and there must have been internal signage to designate them.
