Perfex style Cores

hart parr core

We see this Perfex core used most commonly on the Hart Parr Tractors but you may find it on a Eagle, Heider, Cockshutt, Oliver Case Tractor radiator as well. Originally a film core characterized by stacked round pattern delineated by vertical strips we have replicated this look for the restorers.

The history

F. M. Opitz patented his film style radiator and transferred it to the Perfex company which had established business in Chicago in 1910 before relocating to Racine, WI on the 12th of October, 1912. A. B. Modine was actively involved in research, testing, and design of radiators and a principle partner in Perfex Radiator before acquiring the company. Following a business disagreement with a silent partner at Perfex over how that company should be managed and capitalized, Modine decided to establish his own company.

We make to order. Please allow adequate time for us to build.

Build time estimates [Feb 2025]

Brass/Black Model Ts

Our longstanding foundry (supplier) closed and all production was shifted to a neighboring foundry. Apparently many of the closed foundry's workers were ineligible for rehire by the new foundry due to more aggressive immigration enforcement and the union has no employees to provide. As of 2-20-25, we should receive castings in March 2025 and can resume production then.

In the interim, we have been working with our one-off foundry to have pattern boxes made and these are trickling in in smaller batches and we will produce what we can.

Model As 5-6 weeks

Heater cores ~6 weeks

Model A and 32 Ford Street rods 6 weeks

Common street rods ~12-15 weeks

Tricky customs & complicated restorations ~16 weeks months

We appreciate your patience as we continue to recruit and train new fabricators and manage the labor shortfall our country has been experiencing.
