It’s been a very busy Summer for the Internet Checker Taxicab Archive, to say it’s been exhausting would be an understatement.  We just completed our first national convention, a multi city venue Checkers from all over the country met in Auburn, Indiana and wrapped up event in Kalamazoo. at the Markin family storage facility.


Over seventy blueprints that span a period of 1946 thru 1978

Earlier in the Summer we received a major donations from former Checker Motors Corporation Plant Superintendent John Logan.  John donated to the club a full set of Checker Motors Corp historical documents: Engineering Change Memos, Production Reports and Graphic Illustrations. In total approximately 10,000 individual documents. During June and July we successfully scanned every Engineering Change Order and all Production Reports.  Still daunting we have made a good sized dent in the scanning of graphic illustrations, all of 1964 thru 1969 have been scanned.


Earlier this Summer John Logan donated well over ten thousand CMC engineering document


Just when we were starting to see the light the end of the tunnel, Chris Markin, grandson of Checker Cab Manufacturing founder and his family made a major donation to the club. On the third day of our convention Chris Markin surprised all by donating over 70 Checker historical blueprint!


Chris Markin and his family’s donation will go a long way in saving Checker History


To say the donation is earth shattering would be an understatement.  The Markin’s kind gesture opens up completely new views on Checker.  The impact is will be great for the exploration of Checker history or the restoration of our cars.

Within the donation we have found a full scale blueprint for the Medicar wheelchair ramp.  One of our members is desperately looking for this information so a proper ramp can be fabricated. Consistent with the Markin family goal of helping Checker owners keep their Checkers on the road, our members will have access to these documents.  Our club will do everything possible to get this content to our members.

The documents are full of new Checker history, much of it unknown to club members including this writer.  Within the inventory, we have found a proposed grille that was actually different the the standard A9 taxicab starburst grille.  Dated in 1957, it was probably designed for the pending consumer car.

We have found within the blueprints a proposal for a new Checker!  Designed in 1965 and designated the A14, the proposed Checker would have been equipped with an entirely different front sheet metal.  The full size scale blueprints depict the grille and bumper layout.  Consistent with designs for all manufactures in 1965, the A14 sported a horizontal grille with vertical headlamps as seen on Ford and Plymouth of the day.

Blueprint Donation Markin

Chris Markin personally presents the blueprints to Club Facebook Administrator Joe Fay


The oldest blueprint depicts a full side view in 1/18 scale of the Model C Airport limousine dated 1946!  The ill-fated rear engine model C never made beyond the experimental engineering buck, but the blueprints depicts a car styled much like the Model D and Model A2. The Airport limo was specifically designed for Parmalee’s Chicago facility based on metrics indicating Chicago entrance ramps dimensions.

Within the inventory we have found a number of comparison blueprints, one in particular is very interesting.  The noted blueprint compares what appears to be an Checker Model A6 to 1951 Cadillac.  We always knew Morris Markin liked Cadillacs, now we can see the Cadillac was used as a benchmark for Checker.

A sincere thanks go out to the entire Markin family. A special thank you to Chris and Joy Faust Markin for also hosting our members on the final day of our three day weekend.

As we have learned with the Logan donation, key to digitization is attacking the documentation in small chunks, over the next couple of weeks we’ll develop a plan to digitize the documents and upload to the website.  Additionally we’ll assess documents that may merit full size color digitization in order to make available to Internet Checker Taxicab Archive members.

Thanks to Bill Beurkens and Ed Fox for supplying pictures for this blog.
