I have one of their catalogs from 1992 and at that time only their full-size bronze barrels could be had with a steel liner. Competition shooters did not prefer bronze barrels with a liner. Oddly, a bronze barrel with a liner was a cheaper version of barrels because they could provide the liner to the foundry to cast the barrel around it. This eliminated the step of having to drill and polish the bore of the rough casting. A bronze barrel without a liner was more expensive since they had to both bore it plus grind and polish down the entire rough casting but again as mentioned completion shooters wanted the more expensive all bronze version. In other words, even though it sound counter-intuitive, a bronze barrel with steel liner was the budget version of the barrel without a liner
All of their ductile iron barrels came with steel liners as a safety factor because cast iron is so brittle.
A half-scale Napoleon barrel without liner purchased with a carriage was $1900. Since they did not list the cheaper version with a steel liner in the 1992 catalog, I have no idea of the cost
A matching 1/2 scale finished carriage was $4300
That would bring the total cost to $6200 minus any loading implements which might add another $500 max. Then one has to figure the cost of shipping unless one would pick it up in person. Unless the costs rose dramatically in 1993 that cost of $10k sounds a bit high. $7k might be more realistic as the original price. As for a current price $7k entered into an inflation calculator comes out to $15k for 2024. However, finding a willing buyer with that kind of money
for what is essentially a fun toy and oversized doorstop will be the problem. I think you'll be lucky to get $10 to $12
Finding an appropriate venue to list something like this is the real problem.
The high cost of professionally made cannons is why many people with home shop tools try to freelance it themselves. The results are usually poor to total suckage because they never bother to acquire any accurate plans.
I have collected small-scale cannons for over 50 years, but until recently, my largest was 1/4th scale. Then, I got lucky two years back and found this 1/3 scale 1861 Parrott with a South Bend Replicas barrel on Armslist. The seller's late father had built it from scratch and had won several shooting competitions with it. Being cast of iron, the barrel has a one-inch seamless steel liner for a bore. The father had intended to build a matching limber but had only built the wheels and axle housing so that was included in the deal along with all the other stuff shown. The gun had it listed at $2500 for over six months without a bite. He had no interest in it and his wife wanted out of the house. I got him down to $1500. I had to drive about 600 miles to pick it up but it was certainly worth it.
There is a guy selling a quality 1/4 scale Napoleon that he builds using a solid brass/bronze Brooks barrel for $6200 Since a 1/2 scale would require 8 times the volume of material to build your price might be very fair but at the same time very hard to get due to the limited market. With the massive decline of civil war reenacting over the past few decades the interest in muzzle-loading cannons has also dwindled.

I'd love to have your cannon but am unwilling to spend that kind of money nor do I have the room to house it appropriately. I already have a two-bedroom patio home filled with small cannons. I'll turn 80 next year so I'm about at a point of trying to sell all of my cannons instead of buying more. I'll probably use one of the big auction houses like RIA (Rock Island Auctions)
you've got to get some wider exposure to get the best price. Your average American today is having problems just dealing with the price of a dozen eggs
I see cannons occasionally listed on Guns International
Also eBay reaches a worldwide audience. and they have a section devoted to black powder cannons. You have to call it a signal cannon as if that's all it's for so eBay will ignore it. There's hardly a cannon listed that won't shoot a projectile but It's a hypocritical game that eBay plays so they tell themselves they aren't selling something that's actually a large firearm.
Now that I think of it, RIA might be the perfect way to sell your cannon. They tend to attract buyers with more money than good sense. You might contact them. I used to occasionally bid with them but at some point they began to attract too many nuevo collectors with deep pockets. While they deal mostly in collectible firearms, they do occasionally have cannons--both full-scale and small-scale--even tanks periodically. It's a gamble but you can always put a reserve price on your item so if it doesn't get there it won't sell. They just opened a new operation in Texas to get away from the Draconian anti gun laws recently enacted in Illinois.

It's a shame that Cannon LTD went out of business since they carried a wide variety of cannons from full scale down to 1/8th scale and most sizes in between. They also offer some of these in kit form at a much lower price.
Here's the story of what happened according to what I read online: The husband and wife got divorced at some point, but she stayed involved in the business until she was diagnosed with cancer and eventually lost her battle with it. Then, just a few years later the husband was involved in a serious automobile accident and eventually died from his injuries. He was a hotrod enthusiast and that may have had something to do with his accident. In his catalog he stated that he would accept dragsters and hotrods as partial payment for cannons. The couple evidently had no children. and the estate couldn't find a buyer for the business so the company was dissolved and all the equipment was sold off.
