Think it could be the knobs?
I don't know, I assumed it must be so I looked closer because there have been bidding wars when knobs with short-run logos come up (cigarette lighters for example).
But to me it looks an odd combination. Ok, I don't have an S2 so I could easily be talking total rubbish here (and that's not unusual
) but to me the choke & heater knobs are different styles. The heater looks the same as on my '72 TC, the '68 Elan and is common for the period. The choke is bulkier and the logo doesn't match anything I know although it does come close to some of in the period (60's Fords ?).
I know Lotus had a parts-bin reputation when it comes to getting cars out of the door, but surely they'd have matched up 2 visible components sitting so close together ? It did make me wonder if there's something deeper, like it's off a S1, 47GT or something ? Even so, a choke cable is a choke cable and with the benefit of all this research it seems new ones in the same pattern as mine are available over here, so that's where I'm heading.
