All About Pocket Knives

Hello, I have tried researching this knife, and am seeking some help. The master blade has a weak tang stamping. Secondary blade has none. From what I can read, it might be:
SC TAYLOR
SCARBORO

10 MARKETPLACE is on the blade. I couldn't find anything about this either.
Any help would be appreciated.
About the knife. Bought it in a booth in an antique store. Both blades look original. Half and full stop to main blade. Secondary has no half stop. Both blades have no wobble, great snap. Slanted and pinched bolsters. Curved shield. Brass liners. Great bone.

Looks like N C Taylor ? Couldn't find any info on that name. Beautiful piece! J.O'.

It has that Sheffield look to me.

For what it is worth Etsy has a N C Taylor Scarboro Lambfoot listed and Worthpoint has a couple of N C Taylor Scarborough / Scarboro Razors from eBay UK
