RE: 1/2A Snapper earliest date?
Larry,
I think you got it when it was a new kit. I'll see if I can find some old mags that have it. I remember when Southwest was creating interest by just showing a blank outline. I think the Dil-Bod was their thing before that.
I believe it was released along with the announcement of the Atwood Shriek...WAY after 1952.
There is the sheet-wing Snapper designed by Red Rhinehardt that IS OTS eligible.
