So these 7 are as follows:
2 brass
2 nickel silver
1 copper
1 sintered bronze
1 marine bronze/naval brass
Bodies are all 18350. I have not started cutting heads yet, so option for single emitter long head, or short head for triple or aspheric engine.
Can also choose head crenelations or not, clipped or not, and some design flexibility. PM me if interested in any of these, and we can discuss option for full custom build and cost estimate.
