Fantastic result, good job, I've got some Unitron 142 legs I need to try this method on.

Yup, linseed oil in the shopping cart! I have the blond legs Kasmos mentions. We'll see how they do - and my newly found 6335 and the old 6345 need some treatment as well. It's almost better to see these relatively easy fixes than the extensive renovations.

I use a product called Howard’s feed and wax. It does an amazing job.

BEWARE, I wouldn't do this on blond legs and possibly many Unitron legs. I just did a restore on some Unitron 114 legs and it was a complete different story. I found out that Unitron put a semi opaque golden finish on them so if you do this to them it will make make very dark spots where ever the original finish is chipped. I stripped one set bare and they looked light but then it really really darkened them when oiled. This made me tested a spot on another set of 114 legs that only had some lighter wear and tear, and it's was a NO GO! and I tried to wipe it off with Mineral Spirits ASAP. I think the Lauan/Mahogany or whatever they used is like this and is why so many Japanese scopes have a semi opaque golden or white washed finish on the legs.

 

Another example is my Penncrest has a kind of strange yellow color on them. I think they usually used a one step finish on many of these scopes. Possibly a opaque stain mixted into a clear finish.

Not to stray too much off from the ATCO,

but I took a couple of photos to illustrate what I said about using Linseed Oil on some legs.

Before it was stripped and oiled, the darker leg originally looked like the one it's resting by.

I would even say it was lighter as it was terribly dry and chalky.

Until now I forgot that it was actually refinished with Watco Oil (Natural) but it has the very same effect.

And seeing the difference between the two legs in person is much more dramatic.

While doing the other legs, this where I wiped some Watco on to see what it would do on some scratches.

It shows why you need to be very carefull of what you might try.

Instead, checking them with a little moisture will usually give you a bit of a clue how an oil will affect them.

The ATCO's legs appeared to be only clear coated and the same was true of the Manon legs I had also treated with Linseed Oil.

If you look closely at Unitron legs, you can see that they actually have a semi opaque milky yellow ochre color to them.

At least the two 114 sets I have are like this plus the ones I refinished.

A lot was missing from this kit so it's kind of surprising that it's instructions were still in the box

 

ATCO-Instructions.jpg

The crossed out Eyepiece says OR-4 for 175x and has SR-5 typed below it

A Barlow is also added to the list.

The box doesn't seem to have a dedicated place for it or the Erecting Prism,

but the older wrinkle black versions have a cutout in the accessory box for the Erecting Prism

For a larger view or to download them go to the link below

One thing of note is all of the older 1252s I've seen also have the SR-5 Eyepiece but the linked to instruction say H-5

Perhaps it was just a typo.

A  very aged product sheet was also in the box.

 

It gives some decent general information about telescopes.

I find it interesting that unlike many importers they down play the importance of using high powers.

So much so, it's brought up three times.

They also dismiss the use of a barlow but say it's included by popular demand.

In truth it's more likely because their competion did.

While it says they have been around since 1901,

I wonder if they sold any true astronomical telescopes back then?

I love the poetic approach - certainly translated from Japanese!
