Gits bros MFG oiling cups for ball bearing headstock - Derbyshire magnum or elect lathe

A trip to the hardware store should clear things up.

Gits oilers in that style are available in 1/4-32 thread.
Need to check the pitch of that thread.
Hi, this looks like the close enough one..

Many old english lathes were imperial.. and your 6.63 falls around the .25" .261" it is 10 thou over, but it might be tapered so it doesn't leak.. I don't know.. if it's .25 at the bottom and .261 at the top then it probably is slightly tapered.
You are spot on. I check the end of the thread and beginning section on the top. Diameters are diff.. end is 6.35 mm and top is 6.5mm. Going with 1/4’’ - 32 shown in the picture attached. This has a thread length of 5/32 which is approximately 4 mm.. and the thread nominal diameter 6.35 mm.. guess it will be a trial and error.. I could not find Git mfg cups at McMaster. They have generic one manufactured in Mexico and it’s $20 a piece..
