The mark means that that the barrel is a 12-bore with choke.
This gun has 2 1/2 inch ( 65mm ) chambers.
The gun has issues - the triggers show rust marks for a start which probably means that there will be rust on the locks. There is also obvious wear. Can't see the inside of the barrels so can't tell if they are pitted and don't know what the bore sizes are unless I measure them.
The value is dependent upon condition.....in the UK anyway. In India it's a totally different market and this is obviously a valuable gun.

and proof please
Grumpy was a Registered Firearms Dealer in the UK and traded in the gun business over decades, especially in British guns. His knowledge is truly encyclopaedic and he has written many articles too.
Since you ask for proof, here it is. Again. Both the photos are taken from the most authoritative work on firearms, " The Gun and Its Development" by WW Greener.
I am attaching the excerpts on London and Birmingham proof marks.Page# 298 & 299. The Greener book is available for download on this forum. It is worth reading. If you cannot find it, it can be downloaded from here. This link also shows the exact page where the proof marks are explained.

I seriously suggest you reread that Russian book. If what you say is really written there, I suspect that the man who wrote that book did not understand the original English text correctly.
I can see why you are confused that 12/LC means chamber length here. Before I write about that, I would like you to read the text in the second photo again.
