Found the number 57832....only noticed it after zooming the image... assume its the serial..on focusser..

Tube assembly all original..but tube was in a black effect ,badly worn in places so brass  shown through..had tube painted and the little clamp knob...brass..so it all showed up better in  dark..easyly stripped off if needed to return to orignal..its a working scope at last after being in storage..the mount i made..just to  get up an running.. i  love the objective cell which  can move about a inch  forwards or back , this will help if i get an eypiece  being akward on focussing.. its the machined  'V" on the eyepiece tube that gets me head scratching..just assuming its a hybrid..by way....chap came back to me a week later, wanted the filar eyepiece back.. so he offered me a F5  3' achromat ,an amici prism  2 small achromats and a length of 3' brass tube. .in exchange ....with that patchy black finish on it again...the offer i excepted...!

 i have had an old ross scope for years that i cannot identify, many hrs on web researching ross optics has borne no fruit.

a all brass 4" tube but fitted with a 3" lens cell with uncemented objective working at F10. unusual long focussing tube that extends inside main body with a knurled ring to adjust the 'drag' on the eyepiece movement, it originaly came with a filar micrometer eyepiece.

i have only recentley found a 5 figure serial number on it, just wondering if anyone has any ideas, the objective gives nice views with the plossls i have purchased for it...thanks...more pics on request..
