Mushroom Cook & Serve Coffee cans perhaps?

There are no stamps on the base, but these sure remind me of the Cook & Serve cans.
I'm sure that Jeremy will be able to let me know if they are
No saucers, but I was delighted to find these regardless

I saw these in your studio photo on FB Ev, and wondered if they were 782s or 3618s.

The are the latter, 3618 Reflections cans, matched orginally (1968) with 4610 Reflections saucers and later (1969->) with 4619 Reflections saucers.

I have a six-set of 3618/4610 and a single 782/792 combo. I think Kay has two 782s cans, and it looks as though new skite site member Tina Wells also has a 782.

Thanks Jeremy, I've been waiting for your reply.
I did compare the cup to a Saraband one today and although the foot is the same there is a thickening where the top of the handle meets the cup of the plain mushroom one that isn't on the Saraband.
My last box to pack today was Vitrified Ware and while sorting I came across a few Reflections saucers that look like the 4619, however the cup base was too big for the saucer well and it swam all over the place.  
I think it will be something like the 792 saucer with a wide well.
I will think about this ...  ..... and I've popped one in the last box just to show you

Ev, I stand corrected. You do indeed have 782 cans. Without anything to compare at the time of commenting I saw what I expected to see.

So, correct on 782, correct on being "like" Cook & Serve, but as the (my) saucer has a crown and star backstamp rather than a Cook & Serve one, even though I have addressed them in Cook & Serve topics I don't think it is strictly correct to refer to them as such.

Wonderful thanks Jeremy.
They are vitrified like the other Cook & Serve cans.
I will look at the resources that I have when I get a chance.

The blurb from January 1966 calls this Reflections Lightweight Ware ...
only partial wording unfortunately .... enough however to get the gist.
