It's certainly a "First" model EL3300/00, Made In Holland: AH 02, 16th week 1964. With red badge on TRH corner of speaker grill.
The colour
is brown but sometimes, depending on ambient lighting, it can appear chocolate brown or greyish/brown. Also the first model came with that microphone and a grey leather case too. Also, it doesn't have an accidental over-record mechanism and the motor has a built in centrifugal speed regulator, not a separate electronic circuit speed control.
P.S. The motor may play back slightly slower. If you play a commercial musicassette (1 & 7/8 ips) you will notice and de-constructing the motor is not advisable.
But I have an issue with you !!! ..... yours is 7 weeks older than my one (23/64)..GRRR!
