I have 2 like new .656, Crowe Spaced banjo bridges.
Both are "old wood" maple with Purple ebony top. One is 2.5 grams (10 growth rings) and the other 2.3 (11 growth rings). These are really wonderful bridges but they are in my extra box. They run $36 from the maker but will sell fro $25 each. They will really make your banjo pop.

These bridges are really super, Mike is a very well respected bridge maker.
