Hello all.

I have a few small air-spaced variable 'trimmer' capacitors, obtained some
years ago for a project (one of many) which never got off the ground. They
are in excellent condition, apart from the inevitable silver tarnish. I
thought I might eBay them, but first there are some things I need to find
out.

It may seem a daft question, but are the plastic dust jackets merely to
protect them until they are installed on a PCB, or are they intended to
remain on afterwards? The access hole for the trimmer screw seems to suggest
the latter, whilst the fact that the two halves are held together with
adhesive tape seems to suggest the former.

You can see a photo here - http://tinyurl.com/6qr7m .

My next task is to identify the value of the two types that I have, one with
5 movable vanes and one with 7. They are identified on the adhesive tape as
TL 10 followed by 24/3 and 24/4 respectively, which doesn't tell me a fat
lot. The problem with Googling is you can have simply too much information,
and this is the case here, so I need to narrow down my search in order to
make any progress. Does anyone have any idea where I should be looking?

Failing that, I'll have to blow the dust off the old GDO (it really does
have a grid and not a gate!), fish out some VHF coils and some fixed
capacitors, and do it the hard way!
