As I know, this term is enough old in internet and is not associated with zombie boom.
Interesting information about A5M, but I'm serching for Reisen conversion. Don't like Zeros, but I felt that I need for Model 32 variant in 32nd scale.
And I think that I found a solution: 21st Century kit's nose could be used with Tamiya's A6M2. Only wingtips should be scratchbuilded.
