We're planning to install a new gas range with an electric oven in the spot now occupied by our gas cooktop. The previous cooktop was a broken 70s electric that the owners had disconnected from the power supply. Since we were converting to gas, I didn't take a look...until now! This isn't the wiring configuration I was expecting and am hoping the community can help identify what we have.
Here's a picture of the wiring -- pulled apart/capped to help see them better with multimeter readings noted on for the 2 hot wires:
And here's a picture of the associated breaker in the panel:
Finally, the range we're looking at has the following specs and I would very much appreciate any thoughts as to whether the current 60amp breaker is appropriate for the new appliance:
Electrical Requirements: 220-240V/50-60Hz, 35 Amps
11/11/20 Update: First, thanks to everyone who took the time to comment and add clarifying questions -- really very much appreciated!
We moved some shelving out of the way this evening and found the conduit run. Pretty decent access, actually, in a not-too-scary part of the basement. Pictures below:
And here is the link to the range user manual we're planning to install - the "Electrical Requirements" section begins on page 31:

Official name is: Cosmo COS-F965NF 36" Dual Fuel Range with 5 Burners and 3.8 cu. ft. Electric Convection Oven in Stainless Steel
So, definitely planning to take Harper - Reinstate Monica's advice and "pull and replace exactly the wires you need now."
Again, thanks to everyone for their support! It has been super helpful and I would welcome any/all recommendations and suggestions.
