Lucky Randall Find

[Eire]

I just picked up a box of old tools for a bargain $50. I got a good deal all round, but this knife caught my attention, more for the home made sheath than what was in it.

When I got the box home, I pulled out the knife and saw that what I had bought was a Randall 3 or 4 with a 7 inch blade. Can anyone confirm this? Any idea of how to date it?

Its been suggested to me that trying to refurbish this knife myself if likely far beyond my skill level and i should send it back to Randall to bring it back to condition. Does anyone know ballpark what Randall are likely to charge.

Thanks for any info.
