Ithaca’s response to my email.
“When the assets of Ithaca Gun Company were sold off in New York in 2005, we
obtained only the rights to the M37/87 pump-action shotgun. We received neither
the old company's records nor the specs and records for each individual gun
Ithaca Gun Company sold up to that point in time. We do not know who - if anyone
- received this information but recently, The Center of the West has acquired
limited information on some older modes. Click here for a link to their website:
The Cody Firearms Records Office has rare access to the select serial number records from Winchester, Marlin, and L.C. Smith.

Unfortunately, this means we do not have any information, nor do we offer any
services on any firearms except the Model 37 and 87. We do not know of anyone
that specializes in or know of anyone that manufactures parts for the older
Ithaca guns, including any/all SKB imports. Numrich Gun Parts:
https://www.gunpartscorp.com/ may have used parts, we do not. We apologize for
any inconvenience
