Black grips real or fake

[Edward Tinker]

I think repro, but I am not an expert on it. There are folks here that are experts on them.

2 tests to check, gentle tap them together. A plastic sound is likely they are probably plastic, if bakelite, then when you lightly tap they have a much more 'thud' sound.
Then you can use a hot needle and see if it melts (be careful and somewhere on the backside.)

See the FAQ in the new collectors area that has grips and tons of other information.
