TR2/3/3A What Flywheel is this?

So I'm looking at my flywheel hardware making sure it doesn't interfere with the modified rear crank seal I've just installed and realized this flywheel has the bolts setting in a counter bore unlike the other flywheels I have. Can someone enlighten me as to what I have here? I know this engine had some mods done at some point for racing. It sure wasn't an issue before I tore it down.
Thanks,
Steve Baker

Hard to tell from a picture what flywheel it is, I would say tr2,3,4. AFAIK, they all have the ability to flip 180 the early ones were shrink on ring gear and the later bolt on ring gear. I think that changed with the starter at pre60K and post60K.

I weighed this one and it came to 20# 8 oz so it's been lighted a bit. It doesn't look like the counter bores for the bolts were part of that, but on both of the other flywheels I have the holes for the flywheel bolts sit flush.

Early 3A flywheels weight at 21lbs IIRC. If you flip it over you should see the back side (really front side of the car) is carved out a good bit compared to the later bolt on ring gear types. Later TR4- were ~ 30lbs +-
