I would be extremely surprised if both of those amps are "real" Hiwatts, and not one of the reissue brands (Music Ground, Audio Bros., Fernandes). While the reissue amps are usually good quality, I don't think that they command anywhere near the price of an original Hiwatt. I also find it noteworthy that with the wealth of Hiwatt dating info available, there is no year mentioned on either amp, nor are there any rear panel photos - which would tell you right away whether or not they were the real deal.
