Vision Video Head / Drum assembly

This is a 4-head Drum Assembly unit for professional grade VHS VCRs from 1980s/1990s.
I think some of the VCRs this head fits into are:
Canon VR10
National / Panasonic NV100
National / Panasonic NV200
It probably fits many other models as well, but I don't have the full list.

Vision / Panasonic/National Part number(s): 30524 , AAAA , AIAB , VEH0171 , NV100 , NV200 , VR10 , VH41 , NO526 , NO511
RARE part, MADE IN JAPAN in 1980s or early 1990s !!!

NEW, in factory box. Most (if not all) boxes were sealed with a factory sticker when I received them. A couple of the boxes were opened in order to take photos. Please note that one of the boxes is labeled AAAA , while the other five are labeled AIAB. I don't know if this is a different revision of the same drum model or something else. If you want to receive one of these in particular, please let me know.

SHIPMENT

All item(s) will be shipped by registered priority airmail. Typical delivery times are:
EUROPE (All countries): 8...14 days
ALL OTHER destinations (North and South America, Asia, Africa, etc.): 12...25 days
EXCEPTIONS:
1. ITALIAN customers, please be more patient. For unknown reasons deliveries to Italy usually take longer than to the rest of Europe, i.e. 12...16 days.
2. Good news for AUSTRALIAN customers, usually shipment to Australia is pretty fast, it takes no more than 8...12 days.
If a buyer purchases several items I will combine the shipment to reduce shipment costs.

PAYMENT

In the past I used to accept a great variety of payment options but from the end of 2008 eBay does not permit any other payment options except the following two companies, which they own: Paypal and Propay.
Currently I can accept only Paypal from these two.
Whatever payment option you choose, please, don't forget to write the eBay item number(s) you are paying for.

Here are all the payment options I accept, explained in detail, in the order I prefer them:

1. Paypal.

3. Other. I may accept other options permitted by ebay. Please contact me if you want to pay with any other payment options.
