I would like to provide cast parts for guns that can replace missing or plastic items on guns owned by members of this forum. I would have imagined that brass would be the hands down choice of material ,but I have learned after a year of observation not to jump to conclusions, so I'm asking for what might be your material of choice? There might be more than 1 choice ,for different ,or even the same, application. Some materials are much more difficult ,for 1 reason or another, to use,and that will be a factor. Some will not receive much attention at all but that won't necessarily matter.Once I get an idea of the items wanted and the numbers desired ,I can make a better choice of where to begin. So far ,I am considering Brass ,Bronze, Aluminum,and Pewter. Let me know your possible needs, would you please? Ken
