Variable capacitor #1 No longer available
This is a three section variable capacitor. Looks like it may
have come out of a broadcast radio and appears that the three sections
are probably 365 pF each. Quarter inch shaft with an insulted
coupler. There is a gear reduction drive that takes almost one
rotation to go from minimum to maximum capacitance.
The body of the variable is 3 1/2 inches long, not including the gear reduction drive.
It's been stored in the barn, so needs a good cleaning. The
plates are close spaced, but did not see any shorts when checked with
ohm meter.

Variable capacitor #2 No longer available
This is a very nice single section variable capacitor. It
was marked by someone else as 17 - 212 pF and shows a date stamp
of 8 Juillet 1960. It has ball-bearings on the front drive shaft
bearing and what looks like ceramic stator insulators. There are
only three stand-off mounting studs, one looks like it had been cut off.
The shaft looks like 8 mm diameter (that's larger than the standard 1/4 inch). The capacitor body is 3 inches long.
Overall, this looks like a high quality part.

Variable capacitor #3 No longer available
Here is another capacitor, exactly like the one above, however all four
of the mounting stand off studs have been cut off and the and the drive
shaft has been shortened.
This one has been marked by someone else as 17 - 212 pF and .04 inches plate spacing. The date code is 22 Fevr 1964.

Dials #1 No longer available
Here are two vernier dials. Both imported from Japan, they are
similar, but not identical. They are two inches across.
Both accept 1/4 inch drive shafts.
One of the dials turns smoothly and works good. The second one
turns a bit tighter and only rotates to 95 on the dial, instead of 100.
You will get both as a package deal.

Variable capacitor #4 No longer available
This capacitor has been marked as 200 pF. It has what appears to
be a ceramic end piece with the marking "SK". It has an insulated
1/4 inch shaft and three threaded mounting studs.

Variable capacitor #5 No longer available
This one started out life as a dual section 365 pF variable.
However, somewhere in it's past, almost half of the rotor plates on the
rear section have been removed. It has ball bearings on the front
drive shaft bearing and a 3:1 reduction drive. Close spaced
plates.

|
Variable capacitor #6 No longer available
This one started out life as a dual section 365 pF variable.
However,
somewhere in it's past, almost half of the rotor plates on both
sections have been removed. It has ball bearings on the front
drive
shaft bearing and a 3:1 reduction drive. Close spaced plates.

Variable capacitor #7 No longer available
Hammarlund dual section, marked as 50 pF per section. Quarter
inch shaft with mounting nut for panel mounting. Also has metal
mounting feet with tapped holes. Ceramic insulator.
Looks like it would work well in the upper HF or VHF spectrum, or as a fine-tune cap on HF.

Variable capacitor #8 No longer available
Small open frame variable, marked as 40 pF. Has 4:1 planetary reduction drive. Tunes smoothly. Quarter inch shaft.
|

|
Variable capacitor #9 No longer available
Three of these were available.
Johnson P/N 167-427 marked as 30
pF. Nice little caps with ceramic insulation and two threaded
mounting studs. Also has provision for panel mounting. Only
found one mounting nut. Quarter inch shaft.
|

|
Variable capacitor #10 No longer available
Johnson P/N 301-110 marked as 50 pF. Nice sturdy cap with ceramic
insulation on both ends and has provision for panel mounting. Quarter inch shaft.
|

|
Variable capacitor #11 No longer available
Two of these were available.
Small open frame dual section variable. Manufacture stamped as "Alps C01-0127-05". No info on capacitance
values, the smaller back section only has 4 plates (2 stator, 2
rotor). Quarter inch shaft. This guy is pretty small.
