Been thinking of buying one myself, but the economy and all...
But how would the fission battery recharge?
Maybe there's a photovoltaic cell you can get from the Helios plant. I know the helios plant isn't a photovoltaic plant but maybe there was a little lab that was working on them within the plant. That could recharge your gun, solar scorcher style.
I have the Auto-5. Serial #24XX Browning can't authenticate whether it's first batch or not becuase most of the older records gots destroyed (Damn WWII), but it's gotta be either 1903 or 1904. It's definately one the 20,000 that Browning got in that first order from FN.
How do we recharge batteries now? Plug it in at night. Zaapppp! Zaappppp! Die, svcker! Zaaaaaaaa............Crap! damn batteries!
