I vote no, but the Mojotone aged stuff probably wouldn't look out of place if you spruced up the rest of the cab accordingly. You could probably even get that grill cloth clean; there are a few how-to threads here and on TGP. The previous owner of my Pro Reverb already replaced the rusted hardware; I took it a couple steps further by cleaning the tolex with a non-silicon-based automotive interior cleaner, removed the knobs from the front panel and used some Meguiars "cleaner" wax on the faceplate, and it's looking pretty respectable. Still plenty of mojo, less grime.
My amp looks like dung. A lot of this will clean up. The production date in April 1965. Should I replace the grill cloth as part of a rebuild?
