That's actually a fairly rare one. Most of the 110 RD-50s you find will have a blown speaker. I bought a 110 RD-50 off a dude (with, of course, a blown speaker) for $25. It looked like utter hell - the grillecloth was pissed on, and the cream-colored ridged tolex was a nasty shade of smoke brown. Once I had it cleaned up and re-tubed, I put the heftiest 10" speaker in it
I could find (for a reasonable amount of money), which turned out to be a Celestion Truvox, 150-watt rated. I loaned it to local blues legend Dave Bowker ("The Captain"

for a week, and he was totally blown away by it. He gave me a Blues Junior (with fucked-up reverb tank and nasty tubes) and a Carvin tube combo of some kind (I haven't looked at it yet) (also fucked up)
and $300 cash. Not bad.

Before any of you wankers start pissing yourselves about how I ripped Dave off - I let him make his own deal. Some of the best deals I've ever pulled, I never said a word - just nodded and took the money.
