Other details to look at...
Caliber. .177, or .22?
Take a look (or picture) at where the hammer strikes the valve. Does it have a transfer bar, or does the hammer strike the valve directly?
Is the valve body Brass or pot metal?
There were a couple variants along the evolution of this model, the earlier ones (no transfer bar, brass valve) had a little better rep for adjustment and tuning. Not that the later ones were bad, just that the earlier ones were a bit easier to adjust and keep in time.
Pretty solid revolver in any case. I have both a C and a T in a drawer somewhere. Value, as it looks from here. If I saw it on a gun show table for $35, I'd grab it, much north of that, I'd likely take a pass, but reasonably, probably somewhere between $50-$75. Seals and spares are still available if a fella is willing to dig around the web.
