Can someone tell me where did this Holley 1920 come from?
The 12R… number is a casting number on the carb body (not the float bowl cover); it cannot identify your carb. Sometimes the type number is not preceded by the word "LIST", but I have never seen a Holley 1920 on which the type number was absent. Please do post some pics and look in the correct place for the number:
