Help! Wired George! Keihen Carbs????

Welcome back Wired George! So, can I pick your brain? Just bought these Keihen Honda carbs at a garage sale?
I don't know Honda? But, they are functioning and all parts move free.
inlets measure 26.80mm but then taper down in to the slides.
There are some small #'s I did not write down yet.
But I am hoping just from these visuals you might know what they are off of?
And if they are worth any value?
As I am going to flip / sell them, hopefully.
I took a gamble on them for the price. I did not steal them! Guy was a tough old timer.
Here are 2 quick pictures
Sorry to solicit you.
Thanks in advance for any info from anyone!

From the pics you posted they appear to me to be a set off of CB500 or CB550

Hi GD Thanks! I spent an hour looking around. Seen some lose to the CB 350 4. So I went up the size 350/450/550/ etc.
But Thanks gives me a start to put them on ebay!
Garage sale wanted $25. I said how does this $10 dollar bill look? Guy said pretty good and thanks! So for $10 bucks I can hang them on the wall if they don't sell.

Be careful what you put in your ebay ad. If you list the carbs as CB500 carbs and they aren't, you will get them back and the return shipping is on you.

Agree, I said that to me that is what they look like. Did not mean to indicate that is what they are. You posted they have some small numbers on them. This link has some info on honda carbs casting numbers.

Oh Yes! I know that! I have been on eBay selling since 2001. I always cover my bases.
Thanks!
