It's just been sitting in my garage the past couple years while I've been on the lookout for original parts which don't pop up very often. I finally came to the realization that this amp is never going to get restored with 100% original period-correct parts. Even if I did find all those parts, I'd end up spending twice what the amp would be worth.
I'm not trying to fool anyone into thinking this an all original 64 DR, but I do want to make it look as close to original as possible while being a great sounding player's amp. If I end up selling this amp down the line, I'll be totally upfront about what is original and what is not.
For reference, here is a 1964 Deluxe Reverb.
And here is a 65 Deluxe Reverb.
Notice the cosmetic differences. The most obvious one is the lack of a Fender logo on the grill of the 64. Supposedly this was a cost-saving measure by Leo. The smaller early blackfaces like the Deluxe and the Princeton did not have the logo on the grill. Some of the early 65 DRs came without the logo, but most have it by mid-1965.
The other difference is the lack of the little 1s and 2s above the inputs on the 64. Sometime in late 1964, the 1s and 2s start appearing over the inputs, but I've seen one made in Dec 64 that didn't have the numbers as Fender continued to use up the 'no numbers' plates. Mine is a fairly early one made in May. It definitely would've had a 'no numbers' plate.
