try pushing a few cig filters through the barrel with a light ceaning soloution as often the barrels get full of crusty oil from people excessively using pelgun oil
I prefer a tad of hydraulic oil every now and again on the pivots

Having read about the Canadian spec valve on the latest models, I didn't think there would be a relief hole on early examples. I did check on the back face of the valve - no hole, but as I was doing a trial fit today, I saw a hole on the SIDE of the valve, venting into the trigger space.
That will be part of my low fps accounted for then!
Too many guns, or not enough time?

is it directly opposite the exhaust port and is it a brass or aluminium valve

It is directly opposite the transfer port, and the valve is brass.

just thread it and Loctite a grub screw in it

Glad you said that, I did it yesterday!
With the valve being an original design, it has the aluminium spacer between the nrv and valve spring. If I replaced the spacer with something hollow, would it make any significant difference to the available volume of pressurised air, and the resulting fps?

yes it will increase volume
rather than fit a spacer fit a longer spring from either a current 1377 or use a crosman sear spring(only use for them as they're crap as a sear spring)
what you'll find is that you have to pump a bit more but it will be easier to do
I prefer using the high volume low pressure approach other how yours is now with a low volume and high pressure
