Try Harris Cycles. I bought several 38T 122 BCD rings from them several weeks ago. They don't always have all sizes in stock, but should still be able to order them for you. These are new production, not quite as nice as the NOS ones, but genuine Stronglight. Yes, the inner circle of the Mod 49 is 122 BCD, so those inner rings are the same as mod 93. The mod 105 and 104 also used the 122 BCD rings, and those models were available in some years with drilled rings.

I can trade or sell a 52 ring for the model 99? (BCD 85 or 86 mm) -- if anyone's interested, I'll dig it out and give you more details off list.

Are the 93 rings interchangable with the small rings on Stronglight 49 cranks? That appears to be the case, since the BCD seems to measure out at 122mm, though the design is a little different -- an extra reinforcement ring on the 93 -- might just be to provide added support for some sizes.
