Help! Need Knobs

[slimnomore64]

I have a Hoffman 1950 vintage tv, model 620, chassis 155 that came to me without the channel selector and the fine tuning knobs. This set is a 12LP4 crt blonde table model. I don't have a clue what these knobs should look like. Is anybody familiar with this model that could identify these? I think about all models from this era used the same knobs other than color. Any help with a detailed picture and or source is most appreciated!
