Yes. You just simply go back to where you found the shield and get it.
If it is the shield that your gang had you can simply go back and get it. But if it was the other gangs shield you need to get someone to get you it.
Its a two person quest one person gets the part of shield from one gang and the other person from the opposite gang.
Yes
If you have a belt run it through the handle on the back of your shield and then buckle it. Sling that over a shoulder and across your chest with the shield to the back.
No it cannot. There are only two shields that can protect you from dragon fire, and those are the "Anti-Dragon Shield" and the much more expensive "Dragon Fire Shield". The Anit-Dragon simply protects you from the flame, but the Dragon Fire sort of collects the flame and so can shoot it back out after 50 dragon fire breaths.
to get it back you cant
NO not unless you remember it, Try hard.
A shield was not very important for the knights because it wouldn't protect them from and weapons they used back then. Plus they didn't have the right kind of the mettle back then like we have today.
No.
It looks like his back basically or if you want to see for yourself try visiting some runescape help sites.
You can do one of two things: 1)Buy another shield. 2) Destroy they Like Like and you will get your shield back.
I believe paying members still have access to "RuneScape Classic", the original RuneScape. Other than that, Jagex doesn't offer the option to go back to RuneScape like it was one month ago, two months ago, etc. - it would be too complicated.
