Black <1 + - was one of many Bf109's flown by pilots of II./JG52 to Neubiberg at the end of the war. It carries all the charachterisitc markings with the yellow nose and rudder used by Luftflotte 4 aircraft and the typical small markings of II./JG52.
The roughly sprayed 215 on the fuselage are the last three digits of the W.Nr which when looking at the style of camouflage could be either 332215 or 334215. The fact that the cross under the wing is outlined in white points to the earlier batch, i.e. 332215.
