.. one of 3 my dad has accumulated over the years - he had it calibrated at a local shop, and even had the original leatherette case. I love it - my Fluke does it all, but I just feel more capable when I use the Simpson.

There are times when watching the needle on an analog meter is much more useful than watching numbers change. Easier to see trends, and find nulls, etc. I wish I still had my old Heathkit VTVM.
The best analog VOM ever made was the 260 and it probably still is today.It has a reasonably high input impedance being it's an FET and they are pretty accurate in measurement..

Unless there is a newer version that I am not familiar with, the 260 does not have a FET. I own four of them (260 series 6). They are 20K Ohms per volt. I still depend on them every day. I do own one Fluke for times when Hi-Z input really matters.

Honestly, I don't remember. That picture is about a year old. I see it dosen't have reverb, though.

Honestly, I don't remember. That picture is over a year old. It could be a Concert. I see it has no reverb.
In a dual 6L6GC amp with tremolo/vibrato. I can think of no other Fender amp with that combination. Not in the blackface or silverface era. BF Concert is kinda rare beast. Think the production ran only two years.My 1962 brownface Pro has ss diodes, but runs two 5881's.

I think you're right, it's a Concert Amp. It's not the schematic of your brown Pro, though. Yours has six preamp tubes, and true vibrato.
This Concert Amp had four preamp tubes,and tremolo. It has to be either an AB763 or an AA 763.
There was a Brown Concert for one year(6G12A),similar to your Pro, with six preamp tubes,and true vibrato. I've had those in the shop too.
