Compound Air-Timed Shutter: Who is 'DF'?

[ghktekserv]

I have a lens with a shutter almost identical to the one on this website page:

http://www.skgrimes.com/compound/index.htm

It has the same marking: DF". Who made these; i.e., what is the name of the manufacturer?

Compound shutters were made by Deckel, who also made Compur's, and Deckel was also a partner in Linhof.

I have a number of older Compurs and two Compounds and they are far better than modern Copals or late Compurs.

The sound of a Compound giving a second exposure is the sweetest shutter you'll ever hear
