Times LT Std

Hi there

I am trying to find current licensing details on Times Lt Std.

We purchased this as part of the Font Folio 11.1 - covering us for desktop and flat ebook/PDF online use perpetually.

Searching the web now for this font mostly only throws up sites offering for free, one or two, A-Z fonts for example offer the ability to purchase, which redirects to myfonts.com, however item is no longer available. Of course Monotype own rights to Linotype library now, but thre appears to be various versions of the font faces out there. 
Times LT Std - Bold, and Italic version 1.0 are Linotype AG, where Bold italic, and Roman, both later versions 2.050, and 1.040 both appear to be Adobe systems.

I canot find via Adobe fonts under my CC subscription either.

Can anyone confrim if this font is still available to purchase, if so where from, or, is it now Free to use commercial as many sites indicate?

Thank you in advance

Noel
