When the Tri-Delta adaptor was originally purchased at Olden, The exclusive 
distributor, you were able to purchase any number of additional adaptors for 
a small additional charge.  I recall seeing about 50 different size adaptors 
at Mr. Mainardi's house, so the unit was made to fit even the most obscure 
cameras.  52mm is one of the more common adaptors - but when you get a 
Tri-Delta today on the used market it either has no adaptor or just the one 
it was used with by the original owner.  You may have to rig something or 
bring it to a large camera show and you may find something to rig up.  I will 
see if I have an extra 52mm, as I did get about 15 different adaptors and I 
have some duplicates.  For those who are thinking of purchasing a Tri-Delta - 
be sure to ask about the adaptor prior to purchase - since it will be useless 
if you can't get the prpoer adaptor.
