| X3398 20.11.22. X.3398 - PETO & RADFORD BATTERY PN. {Mr Northey} remarks as follows :- Would you please remind me of the relative values by telling me how much heavier is the P & R battery than the Chloride and how much greater the capacity of the former. My impression is that P & R have endeavoured to produce a better, more lasting and reliable battery rather than a lighter one. PN. {Mr Northey} | ||
