Polar scope for my old mount?

[gijoe50000]

Hi,

I'm trying to track down a polar scope to fit an old EQ4 (some say it's an EQ3) mount; it's a bit of a no-name mount that's used by Soligor, Mizer, Meade, Orion, etc.

 

The mount looks like this (but this one is not mine):

 

 

 

 

 

And the polar scope I'm looking for is this one:

 

 

 

 

 

My telescope is a Soligor MT-750 Newtonian, but I have a 102mm refractor in the mail that I want to put on the old mount and try a bit of astrophotography.

 

So, does anybody know where I can pick up a polar scope to fit this mount, or if they even exist anymore?

 

The same mount/scope seems to be used on the Orion SkyView Deluxe 90mm: 29093_9-98.pdf (telescope.com) but I can't find any part number for it.

 

Does this type of polar scope look familiar to anyone, and know where I can get one, or a similar type that will also fit it?
