I purchased this lens in early 1994. It has served me well. I have just dropped and damaged it.

To positively ID the lens:

1. This is a PopPhot test/review of the lens:

2. This is the lens end:

3. The side view of the lens:

4. This shows the damage:

I can see two possible ways to begin disassembly of the lens.
1. From the lens end with a spanner, or
2. From the bayonet end with a screw driver.

Can anyone advise as to how to open this lens up enough to see and assess the damage, or possibly where to find a repair manual for it?

Thx for any advice on this.
