What would this be worth? Colt SP1, serial under 5k, 98% finish, 20"bbl, etc

Any ideas?

I'm guessing this is a Model 6000 with no spent casing deflector and no forward assist.  (Should be without the block and with a bayonet lug - a preban, green label Colts'.)

Probably worth around $1200.00 - maybe another $100 with the original box and paper work.  This model was made for about 20 years and there's lots of these rifles out there.  I don't know of any adds for a first 5000 serial number but then I'm not a Colts' collector either.

an SP-1 wyth under 5000 S/N no biggie, i got two of'm, they are beautiful........!! as are most Colts...

i got the one most cherry for $1,300 & the other, a bit more used for $1,000
