Antique Cup Harrison Bro and Howson + Whiskey bottle

[dragula]

Hi I found a cup. At the bottom of it, there is written:
Harrison
Broe
 & Howson Eng.
Alpha Plate
E.P.M.S A1
794
Made in England.
On its side, there is also written PM.
Can someone tell me the date of its manufacture, type of material and its worth?

Also I found a stainless steel whiskey bottle at the bottom there is written 'Stainless Steel 8 Oz.'
Again can someone give me some information on it and its worth?

See photos in attachment!

You can find the company marks here !! EPMS would be electro plated magnetic silver !! Not sure what the base metal is but its a very thin electro plated silver !!

The is a flask not a bottle. That may help in your research.

Definitely a flask (stainless steel one).

Are the PM on the side of the cup initials for the owner?

I am note sure what PM stands for. I found this cup buried in my field.

Can anyone tell me the worth of the cup? I am still not sure what base metal it has!

A few dollars at best !! Since it is magnetic and is ferrous metal and has rusted,,with no silver to speak of,, value is little !!
