longhunter:  It is likely the serial number is actually 358048.  It is real easy to misread Krag #s.  The 3s & 6s often look like 8s.  1899 receivers were built as carbines.  What is the length of the barrel on the 1899 you are considering?  What kind of stock is on it now?  What front sight is on it?  Original Carbine hand-guards and rear sights cost a lot on the collector market.  Photos would help others give you guidance.

I wouldn't touch it for $200, 1899 receiver or not.

The barrel is totally screwed - no recovery possible. The stock has probably been ruined as well.

No 1899 Carbine is "rare", but you probably are going to have to pay upwards of $1000 for a complete one. If I guessed that the "one of 2000" is based on info from "Bowers LLC" would I be correct? That gentleman is perpetuating some bad info - he is quite ignorant, and has refused help.

Gunbroker has several 1899s right now. If you wish, I'll vet them for you - I suggest using email. I have no desire to acquire anything more in that line, so I will not bid against you.
