Inventory Disclosure [Text Block] | Note 4 – Inventories LIFO inventories are stated at the lower of cost or market and all other inventories are stated at the lower of cost or net realizable value. Replacement cost approximates current cost and the excess over LIFO cost is approximately $63.5 million and $62.5 million at December 31, 2020 and 2019, respectively. Some inventory quantities were reduced during 2019, resulting in liquidation of some LIFO quantities carried at lower costs from earlier years versus current year costs. The related effect increased net income by approximately $2.0 million during 2019. Allowances for excess and obsolete inventory totaled $5.9 million at December 31, 2020 and 2019. Inventories are comprised of the following:
Inventories, net |  | December 31, 2020 |  |  | December 31, 20 19 |
Raw materials and in-process |  | $ | 18,152 |  |  | $ | 16,474 |
Finished parts |  |  | 51,701 |  |  |  | 47,317 |
Finished products |  |  | 12,833 |  |  |  | 12,206 |
Total net inventories |  | $ | 82,686 |  |  | $ | 75,997 |
