Part I
How to almost turn an original, early Underwood into a “parts gun”

1. Walk into a local gun store, notice several carbines on the wall, see one with tag marked Underwood with flip sight, Type 1 barrel band, highwood stock with I-cut oiler slot.
2. Look at said Underwood, try to remember everything
3. Return home, check books, and head back to store.
4. Look at said Underwood second time, remove barrel band and handguard, and inspect all metal thoroughly. Look over stock for cracks.
5. Negotiate cash price, settle on amount, and walk out door.
6. Print out Carbine Data Sheet.
7. Disassemble Carbine into component groups (trigger housing assembly, bolt, etc.). Note that sling (tan C-tip) and oiler (IU) are correct for 1,378,071 serial number.
8. Take bolt tool, and remove extractor and firing pin.
9. Loosen bolt tool (you might see where this is heading).
10. Cringe as you hear a ping and ricochet as the extractor plunger takes off for parts unknown.
11. Spend next three hours taking apart room piece by piece.
12. Breathe sigh of relief when you notice extractor plunger on carpet in corner of room.
13. Comfort yourself because now your wife can get in and actually vacuum and dust your room.
14. Fill out data sheet, put everything back together, and go to bed.

Part II.
As best I can figure, this Underwood is all original, but I'm willing to let others give me their opinion. The exposed metal shows wear, but the finish under the wood shows very little wear. Some of the shine (particularly on the barrel) is from hand rubbing it with CLP to help protect the remaining finish; no evidence of a repark. Wood is dark, but relatively free of dings and scratches; no cracks as far as I can tell. Muzzle wear is almost nil. The carbine appears to have been carried a lot but shot very little; possibly a guard or parade carbine.
