Please help with marks on English measuring jug

[nich52]

This one pint jug is a measure of some kind. It is stamped 'PINT' and has a small oval mark consisting of a crown over 'VR', which is over the number 57. this can be seen in the picture, sorry it's not very close. It is also stamped 'R.E. Lane, Peckham'

I would like to know what the mark means and what this vessel was used for if anyone who knows would be kind enough to tell me. Can the age be deduced from the mark? I also don't know what this jug is made of. It isn't silver because it doesn't have any conventional hallmarks, but it looks silver - I am assuming it is plated.
Would this have come from a pub or alehouse of some kind? Who could R E Lane have been? Maybe an innkeeper?
I also have two very similar half pint jugs with similar marks. thanks

Hello.

Believe the crown over VR mark is a verification stamp (capacity) used in the UK, usually on pewter vessels.
VR is the monarch's cipher for Queen Victoria.
The number 57 would indicate a county or borough (possibly Cheshire County for number 57).
