Yes, I agree these calipers are primary for historic racing where you have to comply with regulations.
You can have several sets of Wilwoods for the price of one set of these Lockheeds !!
Below is another piece they developed - airintakes for the rear Windows. They bought the commen "ear-intakes" from the UIS vendors, and after deaming them "useless", they developed their own. They have two outlets, one for a closed airbox for the Webers, and the other for cooling of the fuel-tanks, one each side. I have the moulds for both intakes and airbox.
