Not at home so no pics yet . These C-4's are also correct for my 1934 & 1935 John Deeres and I have probably 50 NOS ones . At least !!!! Anywayz the most common seems to be the ones with red lettering and no brass cap on top . Second seems to be the red letter ones with brass caps . Least common seem to be the ones with navy blue lettering . I have about a dozen NOS ones like that and all are no-brass cap types . FWIW in early 34 JD parts books the plug pictured has the brass cap . I will add pics when I get home. On pricing I only buy NOS ones and have paid from $5 to $100 each for them . Navy blue ones are the high end of course . I don't buy the modern-non coke bottle ones .
