Follow-up from HHC 2017 in Nashville - Commodore calculators?

I bought an SR5190R (part no. 201198-03, serial no. 007886, made in England) from eBay after watching Gene's Commodore presentation on youtube. It was in reasonably good condition although the label on the back was a bit worn. It came with an original Commodore mains adapter and faux leather pouch. The original Ni-Cd battery pack had been removed, but I replaced it with the highest capacity three-cell Ni-MH battery pack I could find (Emmerich 255066 NiMH AA 3.6V 2200mAh ZLF 3-Cell Ready To Use Battery Pack).

Interestingly, it uses US liquid gallons and US fluid ounces rather than their British imperial counterparts in its unit conversions to liters, so unlike blackjetrock's m55, they didn't bother doing an imperial unit version of the ROM for this model.
