Homebrew Transmitter-Anyone Ever Seen This Circuit?

I know this is not a Heathkit, Hallicrafters or National but was hoping
someone on the list might be able to help me.

A beautiful homebrew CW transmitter followed me home from last weekend's
hamfest. It is an 80-10 meter VFO transmitter with a 5894 in the final.
Looks like I finally have a use for the spare 5894's in my garage..LOL

In looking through old QST's, I have never seen an HF transmitter using
this tube for a final as I believe it is VHF tube. The rest of the
lineup is a 6AG7 driving a 5763 driving another 5763 into the 5894. The
VFO is a 6SJ7 driving a 6F6 (I think). I have not opened up the VFO
compartment but I doubt their is a tube inside.

Does this circuit  lineup ring a bell with anyone? I plan to put this
thing on the air with my BA receivers. If anyone remembers such a
transmitter circuit from QST or CQ, could you please fill me in. I have
attached some photos of this radio. The construction is superb. It is
missing the plate tuning cap but that should not really be a big deal.


73 and Tnx for any help,
