I recently picked up a 2nd variation Winder musket 1885 high wall takedown in 22 short.  

I’d like to get an additional barrel for it that’s a 26-30” #2 or #3 octagonal barrel in 22LR.  I’ll keep the original barrel and configuration as is and unmodified.

I’ve found Winchesterbarrels.com and communicated with them but would like to know if anyone can recommend other vendors?

I have an additional takedown receiver extension already, would just need the barrel itself.  I’d be happy to find a used barrel in almost any condition, but those see very rare.

Any suggestions for other barrel makers?

thanks in advance
