Hi All,
My step dad was a world war 2 veteran, since his depature in life I have had in my possesion for some time now an old telescope.
Since I am now a amature astromomy I would be quite interested to know more about it, when it was made, its value etc..
I know there are a couple of members here that speaclize in antique telescopes so I am hoping to fish these guys out for some info

The markings on the OTA read the below:
( ? means i cant make it out)
Depression Range Finder MA?? ?????
Telescope Mark 1
Ottways Patent No 2693/1913
T 20
No 466
A Symbold D with a upward arrow?
The scope still works, fairly decent views of the moon and saturn I have had with it so far.
Well, appricate any assistance you may have to offer
