James,
Sorry, the 337A that I have did not have electric trim. Bummer!
But in the future, if you let me know what part it is and also give me a part number, I'll be able to get back to you with an answer if I have it and what kind of condition it's in.
email me at
kkenison@conlaw.com or
kkenison@charter.net and I'll let you know if I've got the right one for you.
Thanks,
Keven
