Tokico caliper ID

[rodekyll]

I have a pair of Tokico front brake calipers.  They are radially mounted and appear to have 30mm pistons (2 per side and 4 per caliper).  They look like K4-K5 (block style) calipers, but there are a number of very similar K-units.  Can anyone help me ID them for sure?

Thanks

I guess I found the question too obscure for even this group.

 I was gonna suggest asking a sport bike forum , since those brakes probably came off of a sport bike. We would appreciate a better pic of the trike now that the new forks are installed , and maybe
a report on the difference .

It's a long story.  I'm writing it, but it will take some time.

It gives the K-number of the 4-pot calipers, but no specs.
