Hi Michael, I am very familiar with what you have, working for the Eska Company from '49-'60 till they sold out to Ertl.
The tractor you are refering to is quite rare with the Firestone tires. Valued at $14,000 - $16,000. With only 100 released in May of 1949 by the Eska Company to select IH dealers as per contract with Firestone and International Harvester they went quickly as it was the first of the highly anticipated Eska/ Farmall pedal tractor. The all Eska Farmall small H pedal tractor was produced in far more greater numbers till 1951. Approx. the same time Eska released 60 of the red generic (which were to be the John Deere A) at department stores in Iowa and Kansas. Hope you find this information helpful.
