They were made from 1985 to 1993, so you might still find one in the used gun rack at your local gun shop, at a gun show, or at an auction (local or internet).
I might be able to help with your question .... "How old is and Iver Johnson 22 model 55 A ? . I purchased a new in 44 years ago in June of 1963.
Generally, Iver Johnson revolvers will sell for up to $200 in excellent condition. Typical used IJ prices are half that. sales@countrygunsmith.net
The 9x19mm magazines are not 100% compatible. The carbine magazines fit into the pistol, but the pistol magazines are too short to be used in the carbine.

Parts are very scarce for this 'Erma' of West Germany made gun. Some parts do show up on Ebay.
Iver Johnson was located in Fitchburg, Mass, from 1883 to 1984, never actually in Boston, but I suppose they could have marked items with the name of a more widely recognized nearby city. The name "Iver Johnson & Co" was used from 1871 to 1891, so your holster was probably made during that time.
Name used by the Iver Johnson Company from 1910-1935 for lesser quality revolvers made by their company.
They didn't. Empire Arms Company was a trade name used on revolvers sold by Sears Roebuck. They were manufactured by Fyrberg Arms, Meriden Arms, and Crescent Fire Arms, and possibly other companies, perhaps including Iver Johnson.
An Iver Johnson revolver in 32 caliber was used to assassinate President McKinley. 2 shots were fired, one hitting his breastbone did not penetrate, the second shot entered lower and damaged a number or organs. The bullet was not removed.
The FBUX letters on an Iver Johnson shotgun is the serial number. Iver Johnson, in the later years of production, used the word "Fitchburg" and assigned a number for each letter as follows: F=1, I=2, T=3, C=4, H=5, B=6, U=7, R=8, G=9, and the "X" was for 0. Therefore, the serial number is 1670.
