Just wondering if anyone has come across the tool that was used to unscrew the lenses from the M19, M40 or M38 telescope.

Was it simply a pin wrench or spanner wrench or a specialized tool.

My issue is I have a M40 Telescope and it's missing the big lens at the large side of the scope. I have a M38a2 telescope that has everything. I want to swap out the lens from the M38 and add it to the M40.

Anyone do anything like this?

Have you tried two small flat head screwdriver? Place one each side in the grooves and apply to appropriate directional pressure.

Yep. The lens is in their pretty tight. I am sure they must have had a tool for this.

You can get a watch makers tool for this, they have two paddles which are adjustable - though name escapes me sure if you trawl ebay with watch maker tool you may see one.

Using a set of calipers might work as well.

maybe a dumb question, did you loosen the set screws on the side?
