Glass RF power triode valves - pair

Glass RF amplifier triode valves.
Price for the two of them. Tested filament good but no other testing done.
The model number is a 4-250A if I remember correctly. They are large handsome tubes and are a pair of the same make and age (as far as I know) and were purchased together.
Price negotiableis you have something interesting I am looking for in part exchange.
