[Milsurplus] Hacked-Up BC-342 Question

[Joe Connor]

I just started working on a very hacked-up BC-342 that was stashed away in my basement. The cosmetics are a nightmare.
 
On first inspection, I see that the 1st RF tube, which is supposed to be an 6K7 (VT-86), is actually a 6SH7. The grid cap is missing and the former grid-cap lead is apparently wired to the underside of the tube socket. 
 
Is anyone familiar with this mod? Does a 6SH7 make sense in this application? If not, what non grid-cap tube makes sense? If the prior owner simply wanted to use a non grid-cap tube, wouldn't the 6SK7 make more sense?
 
As always, thanks for your advice.
