Your scope and mount look great. I had the 451 a few years back, but no mount, and so it was sold. The mount is classic.
Congratulations on your awesome acquisition.

What an outstanding scope and documentation too! Definitely a great representation of the era. We want to hear your first light report ASAP!

Wonderful piece of history that will be be great to use too. I have the 12.5/25mm combination GOTO eyepiece and it works as it should, but only by using the combinations as on the instruction sheet. It is a bit fiddly as a practical dual power eyepiece but still interesting Mark

I have a copied (1959) SE Laslo catalog with the 451 in it if you'd like me to send it to you. Laslo was the US importer for the Hyscore. I'll be home for a few days in mid-June, just let me know.

It also has a Bakelite cell and the focuser is all Bakelite as well. I am not sure if you know this but your focuser might be rotatable, not that you would need it on a Alt/Az but i didn't realize mine was rotatable until one day when i was removing the focuser i heard a low snap/click and realized it was frozen. After a little investigation and cleanup i found the focuser to be rotatable, a neat option for back then. The focuser alone is a minor work of art with its all Bakelite construction, just be careful it isn't as strong as an all metal focuser. Again GREAT catch! Enjoy.

I didn't know, and yes the focuser does rotate. I can spin it 180 and have the focus knob on the left side where I like it, however the mount now blocks the view of the finder scope
And what is bakelite really, some residue of the Carboniferous period, not really coal, yet not quite diamond?
