Strange Heavy Duty Rat Trap Pedal ID Help Please

[New Mexico Brant]

Can anyone please assist in identifying who and when these pedals were manufactured? They are NOS, with what appears to be a baked-on enamel surface finish; extreme heavy duty construction. Thank you for any help!

Early motorcycle?

Very sweet pedal no matter the make Brant!

Maybe from a pedal driven scrollsaw or other tool?
