I need a Gurley tripod to display the first transit that I ever used. A little rustic but solid would do nicely.
Check ebay. They have gotten pricey now that it is chic to re-purpose them for lamps.
My rambling thoughts. If you use the seco adaptor above, don't throw that transit on your shoulder. The bell housing bracket on modern tripods may not be adequate in construction, although they vary in strength.
