Lots of luck with that, especially the price. I have much more stuff than that and can't even give them to anyone! So lotsa luck with actually getting $ for them.
I cannot say for certain which ones are operational. Since they are my uncles and he is no longer around, I am not sure. I have found pictures of them running, so at one point most if not all have been operational.
Have about three or four flat-plate ironers. You aren't missing much being that you have the Siemens rotary ironer. Indeed my ironers see far more use than the Elnapress or Hurley ironer-presses.
seller was never in his life going to get that lot shifted as a group. He will do far better now that things are broken up and on eBay. The latter means potential buyers can pay via PayPal or whatever means accepted then work out shipping. This expands the pool considerably from what otherwise would be pretty much a local market.
The more rate and unique items such as the combo W&D should do well. From just those alone seller may reach the lower end of his opening number to move the entire lot.
