ID these Orion RF PA boards by number?

[ElroyJetson]

I've got two Orion high power RF PA boards and chassis but don't know what bands they are. They'll need repair in any event.

Can anyone ID them by RF band by the board numbers?

First board number:

B19/6PCLD00281E (On the solder mask near the rear of the radio)

Second board number:

B19/6PCLD00279C

If you can tell me what bands these boards are it would be be appreciated.

I'd also like to know what the matching IF boards should be to go along with those RF PA boards,
as the boards were out of them when I got them. I have some IF boards but I don't know which is which.

I have identified the LBIs you will need to refer to to further identify these boards:

LBI-39002:
B19/6PCLD00279C, 110 Watt Power Amplifier (VHF)

LBI-39034:
19B/6PCLD00281D, 80/100 Watt Power Amplifier (UHF)

If you dont already have these LBIs, you can get them here:
