Wild T4 theodolite
Would an interested person be able to attend your class on the date that you pull out the T-4 and BC-4 to display for your students? If so, I'd make the drive to see both of them together.
Thank You Nate,
Once again you come through with some info that confirms I'm not that crazy.
The dark, right-angled eyepiece is indeed an accessory, 90deg solar filter/eyepiece-it screws into the telescope in front of the eyepiece- it was included in the issued US Army T-2 accessory kits, -there was also a daytime filter set with selectable filters for use in different lighting conditions
I described this to some one on the old forum and they kept saying roeloefs prism and I said "NO" Sunshade. You were able to look directly at the sun with this shade on the instrument. Apparently it was only available in the military issued T-2's.
Thanks,
Ralph
I'll try to dig up a picture of the US Army Wild accessory kits (there were a couple different styles).
The more common one came in a custom fitted olive-drab canvas zippered pouch with fittings to be attached to the web belt; and it had specific places for the solar eyepiece filters, 90deg eyepiece extensions, rain covers, manual, lens cleaning wipes, adjusting tools/ pins, chamois cloth, soft brush, and a small vial of lubrication grease. Some of them also contained places for the battery-powered illumination lights and extra illumination mirrors for reading the vertical/horizontal circles.
If intended for use with the T-16, an accessory pouch might also have included the compass which mounted in place of the handle (T-16 is brass and non-magnetic, whereas the T-2 was steel). - I've seen some with and without the compass. The T-2 was sometimes issued w/ the same accessory pouch as the T-16 but without the compass.. that specific pocket often had other things crammed into it.
There was also a cold-weather T-2 accessory kit with large, oversized rubberized slip-on covers for all of the metal knobs, to make them easier to turn with gloves on. It also had low-temperature formulated lubricant.
