I wouldn't worry - it was a "Franken-arm" - made up from various SME and aftermarket parts from this and other models. Also, replacement parts can bankrupt you at tpurchased a heir current prices!
May I have the temerity to ask if you are writing about the arm shown in the images or the SME 3009R arm in general?
Looked right to me aside from the 3rd party headshell.

I own several SME arms including a 3009R - which was purchased via 'e-pay' several years ago, and for which, due to a 'momentary lapse of reason' - I definitely paid too much.
When I finally examined 'my' arm, which came complete with SME packaging, handbook & templates, it appeared to be slightly 'non standard', in that the base clamping arragement was not 'as shown' on all the images of the arm that I 'subsequently' closely inspected. However, my particular example appeared to be correct in all other aspects, and at the time I was able to purchase all the 'correct' bits from SME.
I found that the arm was easier to 'set-up' than a standard 3009 S2 because of the screw adjustment of the main counterweight, and it is allegedly, more suitable for use with heavier cartridges due to the s/steel (heavier) arm tube. The 'R' headshells are also fitted with 2 bayonets as opposed the the single one of the earlier versions.
Whether, the usual higher purchase price of an 'R' version versus an earlier S2 arm is worthwhile, or even an improvement, is definitely a decision for a 'would be' purchaser to consider - given my vintage 'ears' and system I couldn't possibly comment.
