What is this distributor?

I agree and I have to say the one I have (it was given to me) has saved me a few times. Most recently I went to fire my 410 and was on a seriously tight time frame to make a show and the brand new made in america ignition box failed to spark, threw in the chinese stand by and made the show. Now I fully admit if I ran one full time I would want another in the trunk for spare parts but I guess at $65 a whack I could lol.
