...Btw ,what should the drain valve handle look like ?

Might be the light playing me here, but to my eye it looks like the drainvalve handle is slightly brighter, with sharper edges and a heavier "knurling"?
(Which would make it a later version.)

It should be identical to the steamvalve handle, and if it is i´m blind....and naturally lean stronger against the oldest assessment above
