Not a clue, but isn't that something you should probably have asked before buying one 
I'm vaping a brass Derringer as we speak, the concern is lead leaching from the surface and being inhaled. If you search " pickling brass" in the search bar, there are recipes for a solution which supposedly removes the surface lead. I say supposedly not because I doubt the members posting it but because I'm not a metallurgist and haven't studied it outside of ECF.
If I remember correctly, it was @Alexander Mundy who I first heard this from. If I'm not right, sorry for dragging you over here Good Sir Mundy

Copper is bad? Most of our homes water supplies are piped thru copper and all the older homes with copper plumbing have lead solder in all the joints.

I hope this takes you there. My settings are posts in reverse order for display so it doesn't work for me but should unless you have the same settings.

If not, here is the text of my post:

Ok, got a little bit of time and performed the test using EPA Recognized 3M Lead Check Swabs.
These will detect leachable lead concentrations of at least 0.2%.
Below 0.2% brass is considered "Lead Free"
Swabbing a brand new RM2 on the lathed down outside area I got dark pink to blood red coloration on the first swab.
Quote "If the swab tip and/or test surface turn pink or red the test is positive - A HAZARDOUS LEVEL OF LEAD IS PRESENT. In general, when the swab is used immediately after activation, the darker the developed pink color the higher the lead content."
Soaked both the tested RM2 and a second new non tested RM2 (as a control in case the testing removed the lead) in a 2 to 1 solution of 5% acetic acid (distilled white vinegar) and 3% hydrogen peroxide for 15 minutes occasionally stirring then rinsed with tap water.
Retested both new RM2's and got negative results, so the surface lead is gone or at least below 0.2%.
I swabbed the test confirmation card that was included as a double check for the negative result and it showed the swab was active so the negative result is verified.
There is exposed brass inside the RM2 below the ceramic where a milling action was done to allow juice flow to the hole with the removed post, around the perimeter of the ceramic at top, and the drilled air hole, but they are a small area for testing.
All those areas turned the same gold color as the outside lathed down area did after the soaking so I assume the surface lead was also removed.
The questions that remain are:
Will surface lead leach into juice? (I have a feeling the answer is yes, especially with citric acid)
If so, is there an appreciable danger since the area exposed to juice is small? (Don't have a clue)
Has the surface lead in my used RM2 already been leached away by juice? (Out of test strips to check)
Once the surface lead has been leached away or removed, will it leach out of the brass to the surface again? (That would increase the likelihood of appreciable danger)
This is probably way "off topic" and if so what sub forum would be the best one to start a thread for this super_X_drifter?
Just thought I would let you know the results.
