British Western Electric Candlestick

British Western Electric candlestick telephone. This antique telephone came from the UK, it has a steel body & metal shelled receiver. It appears to be all British Western Electric. The transmitter is a BWE No. 1 made in 1923. 4001 is the BWE transmitter part number. The phone itself is a BWE Tele No 2 (manual) revision 2 made in 1911. I think 1020 is the BWE part number. I'm not sure what the arrow is but it may be a government/MOD mark. Thanks to Jack Ryan for decoding it.
