Hello Thierry,
sorry to dissapoint you, but the Sinar numbers are a mess.
I tried to figure out a system with these numbers, as this stuff is swiss made and there is not a lot with out a system over there.... but the sinar numbers are
The kit for the SB 22 contax for instance is 551.43.046 but the plate is 551.43.246
But its not just 200 more for the plate as the
Kit for SB 22 for Rollei is 551.43.043 but the plate is 551.43.237
So no system at all.........
I still believe its for a SB 44
As I have a 43 adapter which is 551.64.246
If someone out here has the numbers list of the adapters for SB 43, 44 and 54H this would be verry helpfull.
Best whishes
You have got me to remember, Josef!
The +1 digit is for the entire adapter KIT, e.g. "247" for the kit incl. the adapter, the needed cables, screws, etc .... The number "246" is then always the corresponding adapter plate alone. In this case I Believe then it is the adapter plate for the SB 43, but still not certain a 100%.
Best regards
Thierry
