Forum:Lost huge serpens - help

So, me and 2 friends were killing Knoxx for the 3rd time to get the trophy. We backed our guys up first so we could reload them and farm him later. While on this 3rd run, I found a Serpens. To make a long story short, while trying to dupe it for one of my friends, I copied over the wrong save file and lost it. I'm not sure exactly what name it was, but I know for sure it had the following stats.

399 Damage

8.8 Fire rate

120 round clip

4X Corrosive

I almost threw up when I lost it. I assume since it's 399 damage, it was a level 68 (highest level a Pearl can be).

I've tried to duplicate it by using WillowTree. I'll try that tonight and see how it worked, but I don't think it will be close to the 399 damage. If anyone out there can give me a hand, or if you have some like this or similar to it, would you mind helping me, or duping it for me?

Thanks. Hard lesson to learn.
