Quote from: BobDelGreco on July 06, 2017, 03:14:26 PMHi,I have this desk stand with a 26 marking and a 329 transmitter. I honestly cannot remember when I got it or how much I paid. I have been searching around for a while but have not found anything out about a type 26. I see 20, 22, 20-xx , 40 .. Anyone have any info? Is it AE or WE? Approximate dates?Thank you! Bob
Quote from: BobDelGreco on July 07, 2017, 11:28:13 AMHi,Thanks for the replies. Is this what you are referring to on the rack inside?If this is similar to the #22, would the #26 make it a special purpose? What transmitter would be appropriate if the 329 is later than the rest of the phone?Thanks again.

The 229 was the uninsulated version.From the rack photo it appears the hookswitch contact assembly is not insulated from the rack, so it would have used an uninsulated transmitter, perhaps a 229, with a single lead connection, probably through a hard rubber "grommet" (bushing) threaded into a hole in the back of the cup rather than through the lug, and probably had a solid lug and perch. You didn't provide photos of any of these details.

I have a 389W mike that's has a #26 perch and another that's says 48D . Have a few others with 7 , 7A , 44a and an odd ball marked 02AB.Andy F. K1WI
