Solid appaloosa's can be registered...
Taken right from ApHC's site...
"Those not displaying a coat pattern or mottled skin and one other characteristic will be classified as non-characteristic (N/C)) and their registration numbers preceded by the letter "N.""
"Solid - refers to a horse which has a base color as is described above pages but no contrasting color in the form of an Appaloosa coat pattern. This horse will need mottled skin and one other characteristic to receive regular papers."
They can't receive regular papers, but they CAN receive papers nonetheless.
How much are you asking for the saddle? If it's $400 or less, I'd say it's an okay trade. But if your asking $1200 for the saddle, that is not a good trade IMO. Yes he's an okay looking colt, but non-registered colts are a dime a dozen. He wouldn't be worth the trade, unless you really want the colt. Afterall, a horse is only worth what someone will pay for it.
BTW: Is the black the dam? If that's the case, she's solid but has papers? But the colt can't be registered because he's solid? I don't want to assume, but I also don't like liars and wouldn't do any business with anyone caught in a lie.
