Carb with no pick code?

Carb with no pick code?
At first glance the carb in the picture below appears to have no pick code.
Is it just a crappy picture or did some carbs have no pick codes? i.e. possibly a service replacement carb.
With all the carb re stamping going on now my first indication of a possible problem is a really crappy picture of the carb number.
Though I don't see why someone would fake a 7041251 carb.

I’m not familiar with your 7041251, but I did find this past post at CO related to your carburetor. It seems the consensus is it was produced for big cars with a 455 AT in 1971.
The picture shown in the attached link shows a faint RC pick code. If you aren’t concerned about the patina on your carb I’d clean the area up a bit and see if you find any mark. Post your findings if you do decide to clean it up.
Regarding restamps, believe me, it’s alive and well today! Some say no one would go to the trouble to restamp just any carburetor, but I suggest the crooks practiced on something—so yes, beware as you could be buying a carburetor that is not for your particular use.
From the looks of your carburetor it appears to have been undisturbed for a long time.

Hope this response helps, and perhaps others will respond with their opinions.
Happy Motoring!

tnswt is correct regarding application. I have two 7041251 Rochester Quadrajet carburetors (one on my 350 cid the other on my bench - which I completely rebuilt). The 7041250 was used on the 350 cid while the 7041251 was used on the 455 cid. I choose to use the 7041251 on my 350 cid exceptional performance. The delta between the two is the jetting.
It's possible those carburetors may have no stamp & are service carburetors or they may been been used on a marine engine - I really don't know. My carburetor is stamped:
7041251 RC
0351
A couple pictures taken after I bought the car and before I removed & rebuilt the carburetor.

Ok - thanks for the feedback
FYI - this carb is on ebay now: Used 1971 Oldsmobile 88/98 Carburetor 7041251 3640 date 455ci V8
I noticed there is a chip in the top which looks like it won't affect performance but at that price probably not worth it.

You didn't ask for this information, but I'll solicit my opinion to you. I think the carburetor you're purchasing is about twice what the true asking price should be. I'd value that carburetor @ $100 tops. It's a parts/non-working carburetor sold by an individual with no experience in carburetors. Despite the claims of things are "moving" freely, the carburetor looks rough. It's going to take a complete overhaul & rebuild to bring it up to any performance specification (you'll need to dial it in). If you have the capability to evaluate what the carburetor needs after it arrives & you're comfortable with the working parts, you're good-to-go; if, on the other hand, you have limited familiarity with this carburetor and you're looking for a "so-so" bolt-on carburetor & a simple rebuild, you'd be best served to steer away or offer the seller $100.
