update, these seem to be reproduced-- search Lucas 35978 or (as an extra Mangusta stalk I have dated 1967) lists 34827 as the part number...possibly the variations are whether the stalk is "bent" or straight (and it seems that Mangusta had both, at least 8ma1076 and 8ma1074 are straight (at the 9:00 position compared to the steering wheel), 8ma1046 was 'bent" (so ending up at about the 10:00 position).
Price for the repros is healthy--about 800 euros....
