Muzzle Loader Cleaning Kit A Lady Is Going To Sell Me These Guns But Her Nor I Know Anything About Guns..can You Help?

A lady is going to sell me these guns but her nor I know anything about guns..can you help? - muzzle loader cleaning kit

Ok, my boyfriend wants a manager of the mouth and a gun. I thought it was one of them for Christmas for him. I found a woman whose husband died several years ago and wants to sell their weapons. Here's the deal:

At least 6 weapons (not sure how many)
- 54 caliber cannon loader
- 357 Magnum
-22 Rifle
-12 Caliber rifle
Something -16 Gauge
"I do not know the others, but it is at least one other

All these weapons are under 28 years
All weapons have soft cases (except 357), is a difficult case and has multiple cleaning kits

She wants $ 450 for all above-mentioned
I had no intention of spending much of my friend, so I thought I could sell him a muzzle-loader and 357, but my question is: Would it be in a position to the rest, some get something for my money, because I want to spend that much and stuck with 4 + weapons. You could give all my rights, but I need the money.
