TEAC V-377 FRONT CASSETTE DOOR

Used in the Tascam V-377 though maybe common in many other models of this period.

The edge breaks inside , so you cannot open on one side the flap, if you shake your unit you will hear the broken bit inside.

This door is common in these units they just change the writing on the front, take out the cog inside, fit the door in, then put the cog back
