Heathkit IM-2410 frequency counter LED 225 MHz

This is a Heathkit IM-2410 frequency counter, in good working condition and good overall physical condition. The front panel is in good condition. There are a few scratches on the case. The counter has an 8-digit LED display. It is specified to work from 10 Hz - 50 Mhz and 20 MHz - 225 MHz (2 ranges). Gate time is selectable .1 or 1 second. I tested it with an HP E4421B signal generator, and verified the counter meets specs. I don't have an original manual, but I will include printouts of pages from the manual, covering calibration, operation, troubleshooting, circuit description, and schematic. Shipping weight is about 7 pounds and will ship via USPS Ground Advantage or Priority Mail to the lower 48 states.
