Indians For Guns

I have a BSA double barrel and i am thinking of upgrading.I am in a fix between beretta or webley and scott or parker double barrel all three with ejectors and are side by side .Also getting a Westley Richards a brand notch up but its from back in the day 1920's(is it worth buying a gun almost 100 yrs old)
How do these brands after westley richards rank top to bottom and which one should i buy
PLEASE ADVICE

The most important thing is the condition of the weapon. Between the three of them you can not go wrong by buying anyone of them. Buy the one which is in best condition. Dont buy reblued gun as these guns have undergone significant repairs and their long term integrity is doubtful. Buy the one which has three inch chambers as they can handle modern day heavy loads.
Goodluck

Thanks.after taking all your points into consideration and extensive research going for parker.
