I currently shoot with a Canon T6 and I want to adapt this lens to my camera but I don't know what kind of mount his is, any help would be greatly appreciated

The device on the left looks like it screws into the filter-thread on the front of an existing lens ... you'll probably need a "Series VIII" adaptor to fit your filter size. The other lens looks like a T2-mount lens, but without a mount ... I don't know of the availability of a T2 mount to fit your camera. A couple more pictures of the lenses, from different angles, might help confirm any identification.

The sun hood appears to be of a Sankyo Kohki Komura lens, either 135/2.3, 200/3.5 or 300/5. If it is any of those lenses, the mount is bound to be m42. A quick google image search doesn't show any of those lenses having the same pattern of rings, as far as I can see. It could be a lens head designed to be used on a focussing mount like the Visoflex.

Looks like a lens head for a Komura 200/3.5
No focusing mechanism, so probably meant for a bellows or something like that.
On the 200/3.5 the head can be screwed off.

There is an extension added to this one.
The actual lens head ends a bit after the second ring down (the second preset aperture ring).
The extension looks like one of the Komura interchangeable mounts meant for the telephoto series - 200/3.5, 300/5, 400/6.3, 500/7
In this series the basic lens with focus mechanism was made with M39 thread to go into a Leica Visoflex-style device, or indeed a proper Visoflex.

I was messing around with it on a Visoflex in fact, using a Nex-3 as a "digital Leica".

To be used with SLR's they were supplied with M39-SLR mount adapters. I have several.

I need to pull out my Komura 200/3.5 to check the lens head thread - it might me M39.

On many if not most Komuras the lens optics just unscrew directly from the focus mechanism.

No idea what the mount end is, but M42 is a good guess.

The hood is indeed the typical Komura triple-duty type
