It looks like a 1970 up Column. Can you confirm the overall length? A 69 tilt should be 33" overall. Also, in 1969 the lock should accept an "E" key section...so maybe you can try to see if another E sectioned key fits into the keyway. I assume it's maybe a "J" section for a 1970 ignition or maybe an "A" section for 1971, but that's an easy test if you have some keys laying around? The blades of the GM keys have a letter stamped on them to identify the key section milling. Only certain key sections fit into the corresponding year of ignition cores. Doesn't need to turn, just needs to slide in to identify the year of the ignition switch.
Also, there should be a stamped date code on the lower section of the housing (in that area under that tape) that should tell you when it was built. It will be a five digit alphanumeric date code like B170S or something along that line. The column switch that accepts the main wiring harness will also be date coded.
Pics of those dates will help. Hope that helps.
