Judging by the shape of the doors of the main landing gear and other details it's one of earlier Fw 190A. of the EJG 1.
EJG1 was a forward operational training unit....Curious (at this point) about this EJG 1: what was it? An hint on page you linked lets think it could be a training unit; also the big numbers on fuselages make me think so. At The Luftwaffe, 1933-45 this unit exhibits an assortment (on 12.44) of Fw 190's ranging from A-2 to A-9! But, again, how were they camoed? And were there occasions in which they participated to actual combat?
forward operational training unit
An "Ergänzungsjagdgeschwader" was a latewar replacement pilot training unit attached to a Jagdgeschwader...so in essence, they were getting "hands on" experiance during their transition into one of the JG units.Oh well! Thank you!
The closest definition for "operational training unit" I was able to find is:
"An operational conversion unit (OCU) is a unit within an air force whose role is to support preparation for the operational missions of a specific aircraft type by providing trained personnel. Operational conversion units teach pilots how to fly an aircraft and which tactics best exploit the performance of their aircraft and its weapons."

About "forward":
"directed or facing toward the front"

Therefore, it looks like an advanced training unit, on occasion "practicing" on the front. About camouflage, it looks like quite varied.
Here is a couple of pics of the Fw 190A6 5.JG54 , Immola, Finland 1944

and here is one of Fw190A-6- 4./JG54-, Finland in Summer 1944.

As you may notice both of them seem to be wearing the standard RLM 74/75/76 camouflage with many paint seals. I would say this way for correction of already applied camouflage is very likely for most of the early Wurgers.
The basic set of colours for the camo was the RLM74/75/76 and was applied in a factory.. The dark green colours RLM 70/71 were applied in Russia but not for all planes for instance. Also in many cases the green coats weren't applied overall and the basic camo could be noticed at the tails for example. What is more those planes in Russia could be painted with other than the two green colours at tops. Therefore a pic of the particular plane is needed because there wasn't any rule for the camouflage lauout especially for the JG54 kites.
PS. Please note that the RLM 74 Graugrun ( Grey-Green ) was a quite dark paint and applied freshly looked like a dark green colour. As a result all applied seals could look like a dark green paint applied if compared to the already faded RLM 74 coat had sprayed earlier. This can be also a reason for misinterpreting the B&W images.
