Holley 4BBL Carburetor 6R-3738B, (4781 OEM 850?) Mechanic, Rat Rod, Estate Find

Description

This is a Holley 4 bbl double pumper # 6R-3738 B. I did some research, one person on a car forum claimed that this carb is almost certainly a 4781 OEM 850. Another source said it was a 650-800).
^
This is an estate find, and this carb was found in an Estate sale shop with many preemo auto parts. I did not break it down to check inside, because that would have ruined the gasket seal. However, the thing LOOKS CLEAN, and looks ready to install.
^
I CANNOT CLAIM THAT IT IS REBUILT, RESTORED, OR READY TO GO ON A MOTOR, just that it LOOKS that way. Look at the pics, you will see what I mean.
^
I am not a mechanic, so I do not even know if it there is anything missing.
BUYING, REBUILDING, AND INSTALLING CARBURETORS IS NOT FOR NOVICES!
^
IF YOU ARE A NOVICE, THIS IS NOT THE CARB FOR YOU.

A WORD OF ADVICE:
If you see something that you like and it is a price you can afford....BUY IT!
Because, while you are trying to carve a few pennies off of the price, someone else comes in and buys it at full price. I have seen this happen over and over again. Many of my items are very hard to find.

Faster Delivery:
I must get my items to the Post office before 1:30 pm Mon-Friday. That means in order for me to have time to prepare your package, I have to have your payment before 12 noon, for the package to go out THAT DAY.
This means that if you can get payment to me before noon, the item will come to you one day sooner than if you make the payment after noon of the same day. Of course, if you order at any time from Friday noon through Sunday morning, there will probably be an extra day or two delay.

My Offer Policy:
If you choose to make an offer on this item, here are some things you should know:
I do not have time to play games with multiple offers.
^
1. I will decline all offers for less than half of my Buy it Now Price.
2. I will decline any offer that requires me to pay the shipping.
3. I will negotiate and make counter offers with those who offer at least 75% of my buy it now price.
4. If I give you the same counter offer twice, that means that that is my bottom price FOR NOW.
5. If you do not like the price on my item, wait a month! In many cases I reduce the price somewhat; but by then my item may be sold to somebody else!
